I can lift the car about 4-5mm before the front tire loose contact. I use medium tire on post and hard tire on front. At front i have the hard central spring. This weekend i try your suggestions. Thanks for the help
Hi, sorry I'm replying so late but I hadnt seen that there were new postings in the thread.
Dump the front centerspring and only drive the normal front springs. I even got rid of the center damper as well and my car is driving very well on the track.
If you can raise the chassis about 4-5mm before the front wheels loose contact then there's part of your problem.
You gotta see it like this, when you're accellerating the front of your car will be raised and the back pushed down.
In your case the front can raise about 4-5mm, it wont, but all grip on the front tires will be lost even if it lifts too much and 4mm is way too much.
Make sure the chassis can only raise about 0.5mm before the tires go up (with the 2 screws on the lower arms...). You can tune this a little to your driving style but 0.5mm to 0mm is what I usually drive.
That'll help a lot, after that: harder center spring or softer fronts.
I would drive MH rear and M fronts, but I only drive on carpet.
I'll write down my setup this week and make sure to post it here. Overall I really stiffened up the rear, run 32shore pink rears (comparable to the MH rears) and yokomo M's in the front. Strange thing is, my car started to drive really well when I only sauced the inside of the front tire!! The front is glued without the tendency to be too agressive or flip.
