JZA80 Bilstein springs

Postby UTERUS » Fri Aug 27, 2010 2:22 am

In my uzz30 i have supra bilstein struts, the body has had various grooves put in it at some point so the height is adjustable with moving the spring platform up and down.

I need stiffer springs, i'm not sure what brand they are but they are red.
I'd like to put the front springs in the rear and get heavier springs for the front.

They have also no doubt had a hard life, is it worth getting the struts rebuilt? Can the damper level be adjusted while it is being rebuilt?


Flag all this and just get BC's?

Sounds like they could be TRD Bilsteins. Or possibly sport Bilsteins.
I can't recall what colour the TRD springs for those are, 2jayzgte will know.

Either way, yes they are rebuildable, and yes you can get them revalved at the same time. A revalve alone was about $80 each when I was at Autolign.

Bilstein are usually setup to run a standard spring, if you give me specs i can check yours.

You can also re-valve the bilsteins firmer for $90+ each
We do it at work.

The TRD Bilsteins should be a grey/blue type colour and they are an inch shorter than the factory yellow TT Bilsteins and run alot stiffer damper rate.

As the previous poster said if they are yellow then there the factory TT bilsteins if you are going to revalve them goto the TRD/English site and use the TRD damper rates and Spring rates as a guide.I run those rates in my car and it'll stiffen the car alot.

They are abit bang crash at low speed but when at speed there really good zero body roll and on the track they are a really good comprimise for street and fast road/track-day set-up.

They are yellow struts.

So really i need to take them all to autolign and get them to test the spring rates.

HSD/BC use 15/16kg front and 9/10kg rears from what i can find so i guess that is what i would aim for.

It's not exactly a road car anymore so i'd be happy with firmer suspension.
