Project Boxster Club Sport

Our Boxster ClubSport project car has moved on to a new owner who will be running the car in West Coast events. Look for the massive rear wing and of course our trademark ARLAN Motorsport logo on the wing end-plates as seen at club races throughout Porsche Club and Pro Racing.

Project Cayman Cup

As you may have guessed most of the work on the project Boxster CS is directly transfered to the new Cayman project. With the new 987 cars getting the same new front subframe and stabilizer bar configuration as the 997's the problem of twisting the boomerang plates of the old 986/996 front end is now gone. The rear suspension is basically unchanged and still needs the addition of a support for the rear subframe, but we'll be back here with more news and a whole new project to sink your teeth into. As suppliers to the French Cayman Cup Series you find our products in use around the world. Look for our new project car - details coming soon!

Our Goal

We have developed our interpretation of what we believe Porsche might have built had they offered a Club Sport version of the Boxster S. Utilizing as many off the shelf factory Porsche pieces as possible we have created a car for track days or autocross, while maintaining a civilized manner as a daily driver.

A little glory from our 914/6 GT days

In the mid-'70s we ran a 914/6 GT (see About the Company). Ever since the Boxster was launched in 1997 we had ideas of building a car based on the success of our street and track 914s. We have always felt that the midengine Boxster should enjoy the same success as the 914s when you would find 30 to 40 at any Porsche Club trackday event. We have taken much of what we have learned in 35 years of Porsche tuning, 7 years of running our factory GT3 Cup cars in Porsche Owners Club Cup racing and added the latest Moton suspension technology to make a very civilized daily driver.

Boxster Suspension Tuning

This car was used to devlop the Moton Club Sport dampers for the Boxster/Cayman models. If you aren't familiar with Moton dampers (shocks) they virtually own GT and Touring Car championships world wide. FIA N-GT, GrandAm GT, British GT, Belgian GT, Speed GT, Speed Touring Car, European Touring Car to name a few in 2004. Their new Club Sport line uses the same technology as their famous Motorsport line, but at a price club racers, autrocrossers, or high performance street car enthusiasts can afford.

Look for the 997 GT3 Cup car of Bob Fiaeta (2007 IMSA GT3 Cup Challenge Champion) in their new 2008 CareLevel Racing 997 GT3 Cup cars beginning the 2008 season at Sebring in March. Again running Moton dampers.

Eibach ERS Dual Springs on each corner

We've moved to a dual spring setup as we increased significantly the spring rates and this provides a smoother operation of the coilover unit particularly for street driving situations like driveways, manuvered diagonally to avoid scrapping the splitter where you don't want noise from the spring setup startling your passenger.

Tubular Adjustable Stabilizer Bars

To setup the balance of the car for maxmium grip in low speed corners we've added a larger front stabilizer bar with new bushings. We actually have the same diameter rear stabilizer bar, but this bar can now be set softer than the stock bar, which is necessary for street driving. It can then be stiffen for road courses for track days.

To remove any preload once the corner weight settings have been completed and were ready to reconnect the bars we've added new adjustable monoball drop links. The length of the drop links have been increased to compensate for the changes in geometry once the car has been lowered. Further the suspension droop has been limited with spacers inside the Moton dampers to maintain geometry.

Boxster Brake Upgrades

Borrowing heavily from the 996 GT3 Cup we have uprated the brakes with Calipers and Rotors front and rear from the 2001 996 GT3 Cup. We added stainless steel braided brake hoses and replaced the brake fluid with the same GS610 we run in all of our race cars. Performance Friction brake pads are used exclusively for the track, just as on our GT3 Cup racecar. Brake cooling is aided with the larger brake air scoops from the GT3 Cup car as well. We will begin offering a new performance brake pad for street use on all late Porsche models that gives similar stopping power to the PFC 97 Compound race pads but with a special compound to keep the noise very low.

Boxster Engine Tuning - Revo Engine Management Software

While working with Revo Technik to develop a full range of engine management software for 1999 and later eGas (drive-by-wire) Porsche vehicles, and using their now legendary flash installable software we have done a few special things with our project Boxster Club Sport.

We added a set of tuned headers, 100 cell cats, and a sport muffler (or open exhaust for track days). Subsequently we have found that the Porsche factory muffler actually out performs the aftermarket mufflers, so we are now only changing the headers and the 100 cell CATs. We've found it necessary to modify all aftermarket CATs by moving the location of the secondary O2 sensor so that the sensor is shrouded by the end of the outer housing of the CAT instead of downstream as they are on European models. This prevents Check Engine lights because of "Slow to Warm-up" errors with US Ultra Low Emmissions vehciles. Now the engine (with no internal modifications) and Revo's Serial Port Switchable engine management software produces an additional 31.5 wheel horsepower (around 300 flywheel horsepower) and more importantly gobbs of midrange torque that transforms this car.

Further with Revo's Advanced Serial Port Switch technology you can now purchase an optional Revo Select Plus for Porsche that comes with Windows(tm) software that will allow you to further tune your engine to match hardware enhancements as they are added. For example you can tune for 100 octane unleaded race fuel using the built-in Revo "data logging" capability, then upload your changes to the engine control unit. Next you can save those settings to your Revo Select Plus and have that setup any time you take the car to a track day. Click here for more info on Revo Technik.

Aero Dynamics

Aero upgrades were fairly straight forward, first replacing the original Boxster front bumper with the 2001 996 GT3 Cup front bumper that provides additional downforce plus we've closed off all of the radiator venting under the front of the car to reduce lift. We added the front splitter from the 2005 996 GT3 Cup.

Next we installed the Aero Kit II side skirts to keep air out from the underside of the car. To further reduce lift from air under the car we added the 997 under trays to create a flat-bottom on the under side of the car. To finish the car in a way appropriate for a Club Sport model we replaced the rear bumper guards with the painted style from the limited edition "550 Anniversary" Boxster in the matching Carrera White color.

The photos are the right also show the huge rear wing intended for track days only. This wing is built to the maximum dimensions specified in most Porsche club race rules, by Dwain Dement at Vision Motorsports in Southern CA. The carbon fibre wing and wing supports can be removed from the fibreglass rear deck lid for daily drivers, or simply swap the entire decklid out for the factory decklid for daily use, which was our preference.

Track Ready Additions...

When its time for track days there are a few more additions called for. Installation of a roll cage (with removeable front section), racing seats - black with matching grey seat inserts and a fire extinguisher. Many clubs require the top up or a hardtop installed, so plans include a factory aluminum top with plastic rear window installed and the original top might be removed to save weight. The factory aluminum hardtop only weighs 50 lbs.
