Track coilovers

Post by Vanne » Mon Feb 06, 2023 1:09 pm

Intrax by far.. though if Penske made custom sets for the front for not insane money, i would have gone with those to match up my rear set. Thirding Martin.. super knowledgeable guy :thumbsup:

not sure where Billies (had them on the car pre conversion) fit in, but sure as s**t not in the Intrax, KW CS /JRZ/MCS crowd.

Thanks All, on a related note. What camber plates is everyone using. Spent last night searching the internet and it turns out, there aren't that many available in the UK. The Nitrons come with camber plates although I need to check if the rears are true coilovers or not.

I second KW Clubsports for regular track use. I bought KW camber plates when I got mine.
They are a bit of a faff to adjust, but it can be done without removing the wheels (albeit this is made easier at the rear by jacking up the side being adjusted).

Intrax come with camber plates :thumbsup:

Apologies for the rubbish photo, I can't find any others right now but they are fully camber and caster adjustable.

Ed, that’s spectacularly clean! Mine look like this, but they were fitted 9 years and 40k miles ago!

For absolute clarity the picture of mine was taken when I got them brand new in April 22 and had first fitted them, I hadn't even turned a wheel on them at that point :lol:

Below is what the first set looked like when I took them off after 9 years, 50k miles or so and 3 owners, some of whom clearly skimped on maintenance and cleaning...! The beady-eyed amongst you will note one of the dampers is seized solid with the helper spring compressed, explaining why it was a ridiculously firm ride before I replaced them!

Then it’s Beedub who puts us all to shame!

They’re very corroded. Here’s my leaking rear at 35k miles and 7 years showing some corrosion of the spring despite the liberal application of an aerosol of oil from the damper!

Coilover covers, after spraying the dampers and springs with ACF-50, will keep them tip top. Or the fronts at least as obviously the rear springs are exposed.

I'm running true coilovers at the rear as well - mine got properly cleaned of and doused in ACF-50 before winter hibernation.

I was planning on fitting coilover socks (I have a set waiting to go on), but speaking with Martin @ MS Motorsport he said they're not a good idea as they trap moisture/condensation.

I figure they're useful for short periods of use in winter, and in combination with regular ACF-50 applications, but will probably get them on and report back in due course !

Should be ok as long as you give them a good coating of ACF-50 first. If you cover them dry and drive for long periods in the wet without removing them then yes, they'll accelerate corrosion.

The covers are easy to detach and refit so it's a simple job to top up the ACF-50 with the car on stands.

Yes indeed, an adjustable one is on the list but I'm happy with the balance for now :)
