Product Release: ExactFit Magnetic Phone Mount

In this day and age, everyone has a cell phone; our lives have come to revolve around them. The problem is that there is no great place in our cars to store them.

Rennline has solved this problem with our ExactFit phone mounts. These mounts are tailored to your specific model and do not attach to any part of your interior that will cause harm. Most of our mounts are bolt-in units that can be easily installed in minutes. All critical components are manufactured from metal, so they will not crack or break like most plastic units available.

Wire Mesh Grills- Radiator Protection for your Porsche

One of our most popular items for the newer generations of Porsche’s 911 are our Rennline Wire Mesh Grill Kits for the 996, 997, 991 chassis, along with their 987 and 981 brethren. For some reason Porsche decided to forgo any kind of radiator protection, mounting them right at the front of the car and leaving them exposed to the elements and road debris. With our experiences on-track and on the road, we saw the need for a custom tailored kit. Our grills install behind the front bumper but in front of the radiators to provide maximum protection while maintaining a factory fit and finish. Unlike other kits on the market, we don’t use any tape or glue, and no modification to the bumper is required. Instead our grills attach to the inexpensive, replaceable duct work that fixes to the back of the bumper, meaning reverting back to stock requires no paint matching or major body work.

A History of Porsche and its Radiators

1996 marked the beginning of a major shift in Porsche vehicle production. The spiritual successor to the 914, the Boxster was a mid-engine roadster that slotted into the lineup below the 911, both in price and performance. Although the 993 chassis 911 had only been on the market for a year, Porsche released the Boxster which was a sign of widespread change in Porsche’s performance lineup.  Up front were two parts that foreshadowed the end to a 35 year tradition- twin radiators mounted up front with coolant pumping through them- COOLANT! And sure enough, when the 996 chassis 911 debuted in 1999 it was the first water cooled Porsche 911 ever.

By changing to a water cooled engine, Porsche risked alienating its die hard enthusiasts but was able to thoroughly modernize the 911 power plant. This had huge benefits in terms of thermal efficiency and power potential, but offered some packaging challenges. To balance the added weight and provide optimal airflow to the now-necessary radiators, Porsche mounted either two or three radiators in the front bumper depending on options packages. Twin radiators, one on each front corner, were standard with a center radiator as optional for customers living in extremely hot climates or who planned on frequently tracking their cars. This setup has marched on, with minor revisions and redesigns, right up to today.


What Makes Rennline Grill Wire Mesh Grill Kits Superior

When we set out to create a product, there is a huge number of factors we consider. First and foremost is function- Rennline parts are designed to be used and abused either at the track or in the real world, but fit and finish, aesthetics, and a host of other design elements. For these reasons, we decided that the only way to achieve all of our primary goals with these kits was to install them behind the front bumper. This preserves the look and design that Porsche originally penned and also allows all installation hardware to be tucked out of sight, taking the OEM fit and finish to another level.

Because we are track junkies as many Porsche drivers are, we needed to ensure there would be no adverse effect on the cooling capabilities of the radiators with our grills installed. Extensive hot-weather testing ensued by setting up the shop 997 to run a number of mesh configurations and monitoring engine temps through the OBD port. We noticed surprisingly little variation during this exercise, and saw almost no temperature difference through several different setups. In the end, we chose to manufacture the grills from a webbing we found had no discernible affect on coolant temps but kept the openings small enough that they would keep all but the smallest of debris out.

Installation Time!

So you have decided you want to protect your expensive radiators, and your engine for that matter, and you have decided you want a very OEM look. If you settle on one of our kits, there are a few basic steps you will need to perform. The first is removal of the front bumper which sounds a lot more intimidating than it really is. This process varies by generation, but a quick search for your chassis and “bumper removal guide” should easily yield photo-heavy DIY guides for those attempting this process at home. Although it can be a bit tedious finding every last clip and screw, the process itself is not hard.

Once the bumper is removed installation of the grills is a snap. Each kit will include specialized install instructions for your specific bumper, and will include all necessary hardware to complete the install. The instructions will show you how to place the grills and will lay out specific hardware locations as well. If you would like to see the process for yourself as performed on our former 997 shop car, you can see our installation video here:

After you have the grills affixed to the front bumper, installation of the bumper is the reverse of removal. The only difference is that the duct work tends to sag as you try to assemble the front bumper back onto the car. It is important to make sure these ducts fit securely into their receptacles on the bumper, so take your time and make sure to support the ducts from the bottom as this often helps alleviate the sagging problem.

And you are done! We find dealerships tend to complete installation in 2-3 hours, while a DIY garage or driveway job can last a bit longer if you have not had the experience of removing the front bumper before. Be sure to take advantage of having the front bumper off to thoroughly clean out your radiators and surrounding crevices since you are in there anyway. Many customers also take this opportunity to give their radiators a quick spray paint touch up to make them look uniform behind the grills. Many independent tests have time and time again shown that as long as the paint is applied thinly, it will not affect the thermal efficiency of the radiators.

Get out and drive!

Now it’s time to get out and enjoy your newly protected 911, Boxster or Cayman without worry of road debris ending your engine’s life. Whether at the track or on the street, you should be covered no matter what the tarmac throws at you.

CAE Shifters: The Shortest Throws for your Porsche 911

If you track your Porsche, BMW, or really any other car, you know the value of precise, accurate shifts. Traditionally the best solution to sloppy OEM linkages has been a variety of aftermarket short shifters that reduce the length of gear changes, usually increasing effort and making the lever more ‘notchy’ as a result. But CAE Racing has the ultimate solution for any street or track car- their CAE Ultra Shifter. A work of art, CAE shifters are precisely engineered to provide the ultimate in H-pattern upshifts and downshifts while requiring minimal modification and changing of factory parts. This results in gear changes that are almost as fast and accurate as a fully sequential transmission but at a fraction of the price.


This particular shifter is designed for the 964/993 C2 chassis


Having the engine and transmission located at the rear of the car means that Porsche’s offerings traditionally benefited from relatively direct shifting. Early 915 and G50 transmissions used a rod style linkage that directly connected the shift lever to the transmission’s tail housing, making shifts anchored and direct. There are certainly improvements to be made, the U-joint style shift couplers, for instance, tend to get loose with age making shifting vague and gears harder to select. When the 986/996 chassis debuted this all changed though, as Porsche modified its rear-engine supercar to use shift cables instead of a solid linkage. Although both of these systems have positives and negatives regardless of model, a CAE shifter can make all the difference in the world to either transmission setup.


Machined from billet aluminum, CAE Shifting Technology has been producing these works of art for a variety of platforms for years now. Combining the finest in German engineering and manufacturing, each shifter is constructed primarily from aluminum to ensure lightness and strength. This from-scratch design allowed CAE to engineer an extremely tight and precise shifter that maintains the factory H-pattern while reducing shifts from a throw to a snap. Their exacting design and impressive results has led to a couple of copy-cats on the market, but nothing matches up to the original in terms of manufacturing quality, precision and functionality.

One of the downsides of cable shifted transmissions is a tendency towards being vague and feeling unconnected. This is because there is no ‘hard’ link directly from the transmission to the shifter- and this problem is greatly exacerbated during hard driving, whether through canyons, over your favorite mountain, at an HPDE driving event, or during wheel-to-wheel racing. CAE addresses this by providing a precise gate on the shifter itself that translates to the exact same movement of the cables no matter where the transmission is in relation to the shifter box. It is beyond impressive that they have achieved all of this while retaining the factory cables- yes, every 996/997 unit is designed to work with the stock shift cables, although CAE does offer its own upgraded units which further highlight the capability of this piece.

Simply put the CAE Ultra Shifter is the current pinnacle of shifter design. Creative engineering combines with artful manufacturing, precise design and gorgeous looks to create the ultimate package for getting into the next gear. Short of investing thousands on a sequential aka ‘dog box’ transmission with straight cut gears, you are not going to find a more track-ready solution for maximum control over your gearbox. Everyone we know who has driven a car equipped with one of these billet beauties, whether seasoned track veteran or casual enthusiast, has been impressed by the accuracy and control these short shifters give you over whatever transmission they are attached to. So much so that merely referring to them as a short shifter almost feels egregious. CAE shifters are in a league of their own, and that is why we have chosen to offer them for sale right along side our own Rennline parts and accessories.
