So contemplating doing the suspension next year and want to accumulate parts. Knowing that vintage wants you to stay true to period what is the max we can do for suspension goodies? Lets call it SVRA rules as they seem to be the strictest....
Bushings, strut inserts, sways, torsion bars, etc. What are you guys willing to.share on setup? I will be running a 2.4 ltr. |

Thats great info guys. Reading the current svra specs they say that sways, torsion ratings and bushings all free. I have bilstein non adjustables all around, sway in front, torsion bars as stock and required (no coilovers in front allowed), and also have the slip on collars for the rear springs. Anecdotal lore says svra doesnt like those but the rules dont explicitly take a position. They also dont weigh in on front upper strut mounts.
My goal would be not to get ultra fancy about it but refresh with polybroze all around and perhaps new sway bar. Car handles well so not wanting to mess too much but i also want to get ahead of failures based on what are certainly old equipment. |
