In 25.5 TC, the same exact car, same setup with thinner rear diff, same nearly everything except body and tires, and it has no traction roll issues at all. My USGT doesn't have the same steering as the 25.5 TC, given the better TC tires, but it still tips like crazy to the point where it goes up and skies on the front lip of my PFM10 body and makes driving competitively when the grip comes up on the black carpet impossible. I've got the fronts glued all the way till I'm touching the outside most tread lines... like literally CA on the flat part of the tire touching the tread lines, and I still have a tip-tastic car.
A fellow racer tells me my spec tires are ballooned in the front, but they're only 2-3 races old! I put a new set on, and it reduced it, but the car still does it.
I'm kinda at my wits end here with USGT. Are the tires just this bad? I literally just verified I'm running the same down stop (travel/droop) on both of these cars, same camber gain, camber, ride height... everything except rear diff because I need a thicker diff in the USGT for corner exit.
HELP. This is nuts. My next go-to is going to be going down in front camber and camber gain (longer links), perhaps some down stop changes.
The TIPY-NESS is the rear inside tire coming up on corners and my car ski-riding the front of my body, and it's just completely dumb.
Suggestions welcome!
Im glad you posted this because i had the same issues yesterday with my T4 18. High speed sweeper it would slow roll on me at apex if i stayed on power. All other corners the back tire lifted. if i touched a track dot in a corner i would roll. I already had a pretty soft car compared to my can am set up. 2.5 front springs/2.6 rear. 1.3 front sway bar/1.2 rear. Wide track width in rear. 5.2/5.4 ride height and 5.2/4.4 droop. I went down to 2.3 rear springs and it didn't really help. I was/am at a loss. so hopefully some good suggestions come out of the conversation as i'll be looking to try something different. Im thinking its a roll center issue for me.
