Aah, I see, and I'm guessing the 200 would get dominated by the 235's. Good thing I bought a sedan body

I would not say that, we had a local boy race at a national race with the mugen mtx3 sedan and ran it in the 235 calss and put a hurt on those boys......

Finally got my full weekend of practice over foams ... the track its this one :











Well ... my Yokomo its performing GREAT on foams, i used front 40's from Ellegi and rears 35's from Ellegi. Other combination that worked on similar way was full Jaco's 40's all over ...

Im runing front solid and rear diff and the rears were eaten very fast.

Next weekend will show up again on the track and will try front one way and rear diff and then front one way rear solid ... i remember when i run foams about 6 months ago i did the same test and stayed with front solid and rear diff option.

The only problem i found its that the rears ended just with 1mm of foam after a lot of running but only on the outside part, because the inside part its about 4mm ! ... the solution its just add camber ? ... the car did not change too much on performance from begining to end ... but the rear tires did !!! ... and the fronts suffered the same effect but just noticeable (very little) ...

Any comments ?

thanks in advance ...

fix your camber until your tire wear is even and you will notice
that your tire wear will slow down a bit. don't ask me to explain
but when the tires are coning on the outside the tire wear seems
to wear down 2 to 3 times faster.

Usually with foam tires, you need more rear camber than with rubber tires. -3 to -4 camber in the rear is normal for foam tires.

For that track, I'd reach for my 1 way front diff. As for tire wear, just change the camber and try to get them to wear somewhat evenly across the tire.

Wow, I had no idea that you needed that much camber for these cars, wont that hurt performance at the beginning of the run when you are only driving on the inside of the tire?

tabushi don't get too caught up in the #'s on your settings
just try to add camber until you minimize the tire coning.

also when the tires get smaller and you have to readjust the
ride height you will notice that your camber should be less than
what you started with on taller tires at the same camber settings
hope this helps. let me know if it works out.

another thing tabushi you probably already know this but to
set your camber on the car set your ride height first using the
tires your running on and then make your camber adjustment.

Yes, readjust ride height due to tire wear and you'll need to readjust the cambers. Not forgetting that you also need to readjust to give more droop.

If say ride height is 5 mm with 62 mm tires and droop of +4, tires wear down to 58 mm, then ride height should be at 3 mm [5 - (62-58)/2]. Droop should be increased from +4 to +2.
