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. |

Another thing - probably a forgone conclusion - Definitely box / reinforce the trailing arms and tie as much of the cage to the suspension key points as the rules will allow. In stock form, the 914 chassis is pretty soft - making it harder to tune. Like I said, I'm sure you've done at least part if not all of that already.
