I dunno piles? It’s the carpet tile, padded back. Firm, and like I said fairly low grip. I use asphalt setups, but, I was told the base factory setup was pretty much what I should run, and it’s not as good as the rear motor book setup! Not even close. LoL

what do you need the car to do? Are you looking for more stability? More steering? Just to make sure I’m on the same page, you started with the below setup?

Sure, NP. Gimme a little bit to get to the track and get my cars to look over the setup and write it out for you.

I used the setup out of the box. Have stood front shocks up one hole.

car pushed when I first got it together. So I stood shocks up and that helped. Now, it’s stability in the direction change in s-curves or chicanes (can loose the rear easily in the low speed stuff if I’m to aggressive with the wheel)and forward bite out of the corners I lack.

BKUK’s advice is a solid starting point. I’d go the same direction he did but maybe with a bit less droop (5.6f, 4.6r). Are you running an aluminum chassis?

I might be mistaken, but didn't he say he was running VTA or USGT?

I think the flex alum chassis is fine but carbon may help if you are still struggling for grip. I’d also recommend trying your Sorex 24s over the Sweeps.

well, I won last night. Don’t have the springs listed above, but dialed more camber in, and went up to 2mm spacer under inner ball stud on front, and zero spacers in the rear. And the car came to life. I also lengthened the wheel base 1mm in the rear and that made a big difference getting off the corner.

now, just have to get some wheel time in with it now that I can drive it. And I have got to find a better motor, cause these guys can run me down on the straights. LoL

thanks for the tips guys. I do plan to get some springs because I think the car can be better with springs. I just don’t see how the kit springs would work on high bite black carpet. Seem way too soft to me for that. LoL

are there shock towers to run the car with SLP shocks? Or the 2017 or older T4 towers fit?

Can't you use the stock shock towers but mount the bottom eyelet to the lowest hole on the arm?
