I’m moving up from 225lb to 300lb springs in the rear to try and combat the rear rolling over and the large amount of front, inside wheel lift I’m getting. Is there a general rule of thumb for when I should seam weld the rear shock towers?

Do you have oversteer or understeer with the current setup?
Adjustable sway bar? |

QUOTE(eeyore @ Dec 4 2018, 03:32 PM)  Do you have oversteer or understeer with the current setup? Adjustable sway bar? I'm the co-driver. The simple answer is both. To make the car drivable and faster we pretty much maxed out the adjustable 21mm front bar. The car has some push now but that was the only way to keep the rear end behind the car in sweepers and put down power as the car has roll oversteer also. Tightening up the front bar resulted in pulling front wheels close to 6" in the air as the rear is still rolling a lot as we got rid of most of the droop in the front by doing this. I would like to play with shocks to get things dialed in more but that's not on the table as an option right now. I think 300lb/in from 225 is too big of a jump and think the Konis will have a hard time controlling the rebound but who knows, I do like a loose car as long as it is predictably so which it was with a looser front bar, it just wasn't all that fast as it wouldn't put power down. The car is fast as I have gotten the top PAX time in it the last two events we have run, it just could be even faster. https://www.youtube.com/watch?v=3hRf0cg7RNU |
