Coilover options Bilstein/KW/Öhlins/RCE/Tein

[Shark_Bait88]

In terms of finding them, I've seen several European sites with them for sale.

Best way is to contact ZF Race Engineering directly though. Or go through one of their sales partners.

Apart from the spring rates, what I don't like about the Sachs and Bilstein is the stock spring size. Could probably lead to clearance issues if using wide wheels?

Our US KW V3s are softer now (they changed them a few years back), so I think US and EU V3s are the same. Good luck!

Thanks for that info. It was the same in Europe (changed a few years back too). Seems like a lot of US websites need updating. Most list the V3 as 6/7 spring rates.

As far as I know, the only differences between V3 and Clubsports (2 way), are the spring rates. And warranty (5 years vs. no warranty at all!). If the dampers are valved different or not would be interesting.

Clubsport is sold with and without top mounts in Europe. Without they are almost the same price as V3 (V3 only about 100€/$ cheaper).

I have also e-mailed several Öhlins distribitors (including their Nürburgring center) to see if maybe they have one set left collecting dust somewhere, fingers crossed

I will definitely keep an eye on your solution! I saw you also contacted Öhlins, let me know what they tell you regarding the new R&T kit.

Yes I was in contact with Nurburgring center too, I doubt they are able to dig any MI20 up. But I think it's great more "complain". MI20 would still be my first choice if available.

Their product manager is supposed to write back to me after the new year as to why and what the benefits of the MP20 is. I'll keep you guys updated.

As for my ST XTA project, don't hold you breath. It will be somewhat slow progress as I am starting a new job, so my january/february will be focused on that. At the moment I am gathering the parts needed, but I don't know when I will have time to do an install, or if I'm even going to do it myself.

I am now also looking into AST 4150 / 5100. Hadn't heard anything about them before, but they seem like a good option? I could get basically any spring rate I want, they're high quality and with a competitive price.
I've read @Captain Snooze reviews on the AST 5200 (double adjustable) and @Jive Turkey on the AST 4150 and they sound great. Anyone else have any reviews?
Any reasons NOT to get them? Has anyone had negative experiences with them?

They don't answer emails. which pissed me off quite a bit.
But there are supposed to be very good ( the 5xxx series )

I was considering JRZ RS Pro until I found that Nitron was looking for a developpement car. I will bring them my car in the UK in February for them to test on it and they ll give me a set of 3 way for half the price with free mounting, geo and corner balance :p

I used Nitron 1 way on my Lotus with super hard springs. Ride comfort was extremely good.
Adjustment range is wide. I found high speed compression to be too high. But still amazing for the price.

I would not buy suspensions without fully custom settings for each client.

AST and JRZ offer digressive valving, Nitron does not.

(I'm in France)

I had the same issue with ast. They didn't respond to emails so I was like screw you.

I ended up with Öhlins and they have exceeded my expectations for comfort.

I went for 70N/mm rear springs.

I respect the AST would have been better for track with firmer springs.

I asked Ohlins France about the TTX, they said they don't make it for the 86.

I asked Ohlins Sweden, they said to contact Ohlins France........

The guys at JRZ are answering very fast with a lot of details.

Quantum suspensions were pretty cool too. Sadly the 86 line is not ready.


Ohlins is a good and easy choice for the road at a fair price.

In Australia MCA is the only option most people consider. Depending on what the shipping costs would be; thats what I'd go for.

Again @brzest, we had the same thought.

I have the exact opposite impression. They answered my questios fast, detailed and friendly.

My only worries was the odd spring rates they offer as standard: 7 kg/mm front, 4 kg/mm rear. That and the problems with getting stuff road legal in Germany.

Ohlins is a good and easy choice for the road at a fair price.

@MaximeT, Öhlins now only offer a very soft setup for the GT86. 4 kg/mm front and 3 kg/mm rear.

I managed to bag the last mi20 kit so was lucky. I was tempted by all these different high end brands but its hard to part with such large sums of cash with untested gear.

I think your an engineer so you're probably able to tune your own suspention but for me it came down to the fact that the ohlins had been tested and work well for most people.

Yes I should have said Ohlins "was" a good choice.

Setting one way is easy. Setting more take a bit more knowledge.

If you're a good enough driver, you can setup your car by asking questions on the forum.

You can always learn suspensions setup in IRacing.

[ajc209]

I wasn't too bothered to setup 2 ways (almost got some ast5200) but as I'm not chasing the last tenths I went with the ohlins. They are super comfy too.

No huge amounts of bump travel though. Im on 400lb rear springs and I calculated 23mm front and 15mm rear bumpstop free travel. The bumpstops are quite soft though. AST never got back to me so I have no idea if they are better.
