When switching from Jaco to Parma tires on a L4 what are you guys using for spacers on the rear? Without shimming it, the tire rubs the lower pod. I think I need about 2mm.
Last week I was running My L4 and it wanted to push like crazy. I'm running pretty much Blackstocks L3 setup. Using Jaco Dbl Pink front and Jaco Pink rears. sauceing(FXII) about 1/3 to 1/2 on fronts and all the rears. Also, runnign ascari body. My buddy told me to try a stiffer rear spring. I will try that the next time I'm at the track. Any other suggestions? Oh yeah track is burnt new ozite. Apprx 90x50 and very smooth.Thanks
I can answer your first question for sure. Yo want your cars total rear width to be 6.77" wide. When you go from Jaco to Parma-your car will become much narrower due to the rim offset. Measure your cars total width with Jacos-then put the Parmas on and remeasure, Make sure you space out the axle evenyl per side till you hit 6.77"
I say 6.77 because thats ROAR max .width
As for question number two-I can recommend a some things.
1-sauce more of the front tire
2-try White or Grey rears or smaller diameter rears.
3-Softer font spring (0.020 works well most of the time).
4-Make your turning circle (dual rate) 3 or 4 clicks smaller.
5-run the front of the car just a tad lower than the rear
6-stiffer center spring (silver).
7-Parma Speed 8 body.
