I believe this is THE most important aspect of spec racing .
I only have experience with the Beefy Sk car but I'm sure their all very
similar .
Check your tweak from the front and make sure the RT front comes up a good 1/8 " before the LF .
Run the rear as free as possible , harder tires , looser diff , less compound , ect ., ect ,,,, you need that thing to pivot thru the corner like it is on rails and not scuff off any speed ,, especially in the Spec motor class .

A hard rt front tire , a grn/ blue lf tire and firm greens in the rear.

Where I Have Been Racing Every One Is Mostly Running Single Pinks On The Left And Double Pinks On The Right.

Doesn't running exotic compounds take away from the whole spec class racing?

last season i ran firm blues on front and greens on back we worked well for me. and the diff. you want it loose enought that you can turn it with your hands and the wteek i used was 11.0 to 12.6 generally the looser you go the faster but also the harder it is to control.... good luck to you ...
