ISC Coilover Cover Length - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Muffled · 10-13-2022, 04:26 PM

I've searched but haven't been able to find a definitive answer.

I want to install these covers over Bilstein B14 coilovers on my BRZ for the winter. They're universal and come in pairs, available in two lengths: 300mm and 370mm.

Is there anyone that's purchased these and is able to give me a definitive answer on the appropriate length?

Did you email Bilstein?

I've seen this phenomena a few times in this forum. Instead of contacting the manufacturer/distributor directly the question is asked here first.

"I'm thinking about buying these Fluffy Dice from the Fluffy Dice Company, located just down the street, does any body here know the size?"

Could be because a lot of these companies are impossible to get ahold of or straight up won't get back to you unless you continuously follow up like a rabid dog.

I hate begging companies to take my money, but it seems like that is just how it is a lot of the time.

Easier to ask to see if anyone here knows.

I assume you want to cover the entire spring length spring perch to spring perch. My B16 measure ~9" front, ~10" rear. The 300mm would be plenty.

That being said, it looks like ISC uses narrower ~2.5" linear diameter springs, those covers may not completely fit over the 90/60mm tapered springs the Bilsteins come with.

I believe I answered this question on insta. You need a pair in each size. One for rear, one for front, as the coils are not the same length. I've had them on my car for 5 years now

Still going through the process of emailing the manufacture is good just so that base is covered.
Maybe you get an answer.
Most likely though no reply.

I use 300mm covers (but a different brand), and they are still a little generous in length.

i got 4x300 on my flex Zs at stock height and there's plenty of length as well
