Which coilover?

[sebastianroher]

I'm debating on going with coilovers for my 71. I am planning on going with this kit for the front: https://www.rsrproducts.com/product-page/bilstein-rsr-front-strut-assembly I'll be using 911SC aluminum trailing arms and wanted to know what would be the best rear coilover setup to go with?

If you want to wait 3 years like I did to get mine from rebel buy them. If not still buy them just from anybody else

Why do you want coil-overs? Are you building a race car? For a street car, stick with the torsion bars.

3 years!?!?!? What was their excuse? Covid? The fact that I've already emailed them and called yesterday and crickets isn't a good sign. Now seeing this post definitely doesn't give me the "warm and fuzzy" feeling about them.

Covid. ChrisP pieced his together from a few vendors back then. I'm waiting on straight Von's but you can add springs later if you want to ditch the TB's.

Do you have a link?

You'll need to reinforce the shock towers on the crossmember if you use coilovers in the rear, since there's a history of cracks/tears in the metal on the tower itself and where the crossmember joins the chassis main in the rear engine bay. Going to coilovers involves a torsion bar delete, and the shock towers were not designed to carry the full rear weight of the chassis+engine+transaxle (like the torsion bars were via the spring plates).

Rear coilover choice is a personal preference based on your own due-diligence (research, purchase choice). You have a long wheelbase (LWB) car, and I believe as long as you order coilovers for an early LWB car, you should be good to go. I don't think aluminum vs steel ('69-71) LWB trailing arms matter, since the angle of the shock tower was likely not changed when going from steel LWB arms to aluminum.

Thanks!
I purchased the reinforcement kit from elephant racing that braces the shock tower as well as the area where the 935 spring plates mount. I am planning on doing these mods while the car is in body work. I also have to weld in the rear sway bar mounts to the chassis.

Sounds good. I also went with 935 spring plates.

What year is your 911?
