Hello
This is my last caal for this problem. I have been using 4 evenings at track to find out some help for my problem. I don't have previous experience of RC touring cars so this is a challenge for me.
We are driving Vintage-class with new "out of box" T2R. Our rules are basically 17,5T sensored motor, HPI vintage 26/31mm tires & wheels, HPI vintage body and 8mm ground clearance.
I have a problem with loose rear end. I have built the car out of box, set up 8-9mm clearance and made few other mods like turnbuckles and front antirollbar from T2 007.
I have tried now lots of different setups, . I have made almost everything to make car understeer but it only oversteers. Only difference I have found is that oversteering is smoother and some how "driveable". Today I tried Tamiya red spiring (11,xxlb) in the rear with 25W oil and silver front spring with 40W oil. No big improvements, just made the oversteering again smoother. Without throttle car is running like with 10-20% motor brake on and spinning by it self after middle corner. When I use throttle in the middle or in the end of corner car suddenly oversteers and spins immediately. I use only 30-40% of steering trim (setting range 20-150%).
I would like to have rather slightly understeering car than this way. Now it's too hard to drive smoothly enough to make decent laps. I have listened lots of advices how I should have lowest possible downstop values and now the shocks are the limiting in the rear. Today I used T2007 shocks with Tamiya spirings and I felt like those were longer?
Well anyway I would appreciate any help with this setup. I feel like I have used all the cards in my hand and don't know what to do.
