Angry Question. Converting Foam to rubber?

Well I just so happened to find out that my local race track is running only rubber this year. Sucks, because I just built a Xray T2 007 Foam edition. To race on a competitive level will I need to change my top deck to the rubber version? Also what other changes will I need to make?

I know adding flex is the key. Is the multi-diff needed? I mean I have no issues following the basic changes in the manual for building the EU edition. Just not sure if the Multi-diff is needed or the top deck to be competitive.

I don't own an X-Ray but here is my take on it. You will for sure need softer springs and thinner shock oil. Probably two spring rates down from the ones in the kit and a 40%-50% shock oil reductuction. A different chassis and or top deck won't be needed. I think X-Ray has standoffs that you can remove to allow more felx if you really want it. A one-way might be be helpfull. Most importantly, go to the track, practice, setup the car, compare your lap times with other people, rinse and repeat.

I will be buying the softer springs that the kit recommends. Then I plan on removing the standoffs. The good thing about it all is my track has their AMB available for practice so I'll have my transponder hooked up. Thanks for the tips I guess they are more obvious then I first suspected.

I've found that some people like running the stiff chassis in rubber and some don't. I'm more of the mind that you can just change your suspension setup to accomodate the stiffer chassis.

I was running an RDX carpet (foam) spec car and managed to get within 2 tenths of our fastest sponsored guy, who was running his T2 '007 setup for rubber.

I'm now running a TC5 without the optional thinner chassis and top deck and I'm still in the ball park on the fast laps, but I attribute the lack of speed there to less experience and my motor isn't that great right now.

Definitely try the car with the foam chassis first and see how you do.

Thanks for the advice TurboT. I plan to head to the track soon, set the car up. Put some rubber tires on, and just keep tweaking the car with my transponder in place.
