Bill, I'm curious about a few things on this car. What camber settings are you going with? I remember with my stock Boxster the max I was able to get -0.6. I'm sure you'll be able to grab more than you need with this setup. What size wheels and tires (DOT R's?)? Any idea on how much will the car weigh with cage? Looking forward to seeing this car at Alameda. Its certainly going to be one of the lightest Boxsters we have seen at a local AX event.
Hi Grant,
Initially, we are going with -3.0 deg in front and -3.25 deg in rear for camber. Spec Boxster mandates that the wheels be of stock width, 17x7 front, 17x8.5 rear. Tires for Spec Boxster are 225/45/17 fronts and 255/40/17's rear. Since I won't be running with POC for all but a few events, I'll be primarily running 245/45/17's front and 275/40/17's rear. This will be the sizing at the track. For AX, we may run a 245/255 combo to make it easier to rotate the rear. I'd also like to try the 255's up front to see how that works.
Inititally, we have the Spec Boxster classed tires (Kumho Victoracers). The last long but aren't the stickiest. We will use these to play with the suspension settings. After finding out what works, we will switch to Kumho V710's for AX and Hoosier R6's for the track, unless Hoosier comes out with a tire compound for AX that can compete with the Kumho's.
As far as weight, it is relative in some sense. Spec Boxster rules say the car has to be at least 2700lbs with driver. We pulled ALOT of weight out of it. I haven't weighed everything yet, but it's a good amount. We are putting weight back in with the cage, and Tony will tell me how much it weighs when all is said and done.
We will be lighter, stiffer, and have the trickest suspension of any Boxster out there at this point in time at an AX. Same for PCA TT events. We won't approach the performance and mods of Chris Murray's car, but this is a Spec Boxster car, not a GT3 race car.
At the AX it will be busy. Both Randal and I will be playing with shock and AR settings. I've made up a matrix to go by for adjustments. We start and keep going. In the morning, and possible all day, we will be slow. But by our last run we will see if we can lay down a decent time.
Thanks,
Bill P.
