I came across a issue when putting the alloy chassis on my v2. I don't run shims under my lower pivots. Well iin front I found that the shock cap hit the shock mount limiting down travel when the shock also had no shims. A little grinding of the mount fixed this.

Default Lower arm shims

Can someone give me some advice on why to change the thickness of the lower arm shims front and rear. I'm running the kit setup on unprepped asphalt with yokomo 28A rubber and a 8.5t. The car drives nice but I could use more on power traction at the rear. I removed the rear sway bar completely and it helped a little but I still could use more rear end grip. I realize this is a lot of power and nothing will make it grip under power like a 25.5 or 21.5. With such low grip I imagine I don't want to lower the roll centers much but I am still a rookie at on road setup. I understand the theory from reading literature on real race car design and tuning, but I have very little actual tuning experience on touring cars. I'm thinking raise rear roll center maybe?

3Racing. They just became available. I was changing from the graphite to it when I found the shock cap issue.

Any recommendations for a good USA hobby shop that sells these?

RaceVTA.com is a local to you in Florida and helps a lot wtih the VTA crowd down there, definitely recommend supporting Greg @ RaceVTA.

The Cero V2 never got an aluminum chassis version. If you want an aluminum chassis you'll have to buy the Krazed Builds aluminum chassis, if they have any left.

I have read a few of the posts in here about the removal of the shims under the lower pivots. I run on med/high grip asphalt with the kit chassis, is this something I should be doing?
