I've been looking at the Tein HT coils. Remote reservoir, independant compression and rebound adjustability (16 each way, 45mm piston valve (HUGE), 895 lb front springs & 671 lb rear springs.

BUT, they don't come with pillowball mounts for the Evo??? I wonder how easily, and how much, camber is adjustable

Anyone have experiance with these coils?

I'm looking for a coilover for Auto-x and for the track.

I believe I saw one of the members of the Buschur team selling them, I think that it was David. Shoot him a pm, and see what he thought. Im pretty sure they are the same ones.

 

It's strange they don't come with pillowball upper mounts. The spring rates they're using are very extreme (16kg/mm at the front is something like >3x the stock) and you would be over stressing the rubber mounts most likely.

In any case, I think Tein do sell them separately.

There is one thing to bear in mind with the evo's suspension and pillow ball uppermounts in general. You see, just becaus it's a pillowball mount, doesn't mean you can adjust camber with it. You can get pillow ball mounts that are either a.)fixed b.)camber adjustable c.)caster adjustable d.)combination of b&c.

On evo's which are mcpherson struts up front, camber is usually adjusted where the two bolts bolt the strut onto the wheel hub assembly (the thing with the wheel bearing in). This is done using some type of washer whcih means that you'll be adjusting them in finite steps, like +0.5deg at a time depending on which washer you put on and where it's pointing. IMO this is a better way to adjust camber, specially if you don't need to change it often. It's cheaper, stronger and does what 99% of us what it to do. I think this is how Tein do it in their HT also.

On some mounts, you can adjust the caster angle (_basically_ the angle the strut makes to the vertical). This is done at the mounting plate itself, similar to how camber is adjusted if done at the plate also. If you want to know why on earth any one wants to run anything other than the stock caster, don't ask me. Get hold of "race car vehicle dynamics' by milliken. It's good for that sort of stuff.

So, to get back on topic:

• -It would be for the best to use pillowball mounts
• -Tein sells them. Others do too, and theoretically should fit, but why risk it?
• -You can adjust camber with fixed mounts.
• -Using both camber washers and camber adjustable plates will probably confuse you/your mechanic.
• -Adjusting camber with the washers is quite simple, but takes longer than with the plate. However, you really should adjust toe and so on after adjusting the camber, so it's not like you can just come in, change the camber and go again. You can, but it's not ideal.

As for experience, I don't have any with the HT's. I've seen Tein stuff and they're pretty well built. Admittedly, I have never seen the high end range of theirs, like the HT and I'm very interested in how you get on with them. They're very agressive in terms of lowering (2 1/4" at the front) and lower less at the rear which will change things a bit (by increasing the rake of the roll axis) by giving it a slightly more lively rear, I'd imagine.

Anyway, I've rambled on for too long now, must get back to work.

Godd luck, let us know how they work out!

 

Thanks guys, I'll let ya know if I decide to go this route.

 

They are special order from Japan. You can get the top hats for them but they cost extra

But I would just look at the Super Racing Circuit Master.
