Stay KW or go Intrax / Moton...

[bryce]

About a year back I asked a similar question to what Im going to now...

My car is currently on KW v3. I've played round with settings but feel I cant quite get what Im looking for:

• I want a standard feel, I don't care for anything more as I wont be tracking.
• I love the stance of the lower car.

I find when I tighten up to get standard handling, its too rough but when I loosen off to get std feel its too boaty (excuse tech-jargon)

Ive spent the past few evenings studying various posts but its difficult to get a concise answer. I find Thorneys posts useful as hes had vast experience with different kinds.

Based on my wants, what should I do?

Try standard with slightly lower intrax springs?

I thought that was a huge no-no ?

Very very cheap to try and see. They won't make your shocks explode or spontaneously combust

Have you thought about the bilstein b6 kit, its an inverted mono tube design, probably good for road use, its non adjustable. Would guess it will last much longer than almost everything else on the market. If you went with intrax springs, it would be lower too

When I did my research (aka pub chat!) I did hear from a number of people that the KWs were a bit harsh. I opted for the intrax units myself and am more than happy.

Sadly whilst I've had lots of different suspension setups over the years they've all been on different cars, different spring rates etc so difficult to make an assessment (not to mention you need a decent driver!!) but what I can tell you is that intrax, ohlins and exe-tc all make kit which seems a little more tailored to the guy taking a road car to track.

Find someone with intrax and go for a spin I reckon. I'm in essex if you're close....

My recommendation would be to buy the best you can and research best spring rates for best ride for road or track depending on what is your key requirement.

I'd say Moton are probably the best for M3 but complicated just like 4 way Intrax, KW Clubsport very good quality but suffered due to difficult adjustment tools and process, and maybe not quite the best range of damper adjustment between road and track making road use a bit harsher than optimum.

Intrax 2 way are a very god unit road and track, springs 100 front and 50 rear or 150/75 for more track biased. Don't buy aluminium damper bodies as they corrode on road use but steel or s/s excellent alternatives. They are track units so you may need service every two years to keep them workin to the best but all a/m units really don't have the longevity of OEM units.

Nitron are great dampers, they had trouble getting M3 dampers right but Oneils seem to be ok, even though he can't keep up on kerbs

Avoid HST and D2 as generally they are not serviceable nd cheap parts.

As for Bilstien, ask Matt but they seem ok for Sunday afternoon leisurely drives

Thanks toplad, but if I wanted standard look I think I'd be happy enough with STD susp. From what I can remember anyway it was more capable than me.

Thank you Titan, seems to be the general consensus so far.

Thanks shimmy. By complicated on motion what exactly do you mean? And as both you and lawsy have mentioned spring rates, does anyone know the v3 rates so I can get an idea of scale in mind.

Thanks for all the advice so far. Hopefully matt can chime in with his experience.

Any intrax users in Scotland / north area too for a joy ride!

For a car that is never going to see the track then what lawsy said makes sense, however if going Intrax you can comfortably run less than 100/50, 90/45 or even 80/40. 150/75 you quote can't be right for a road going track car, the ride would be horrible, I drove my car to Spa with softer spring rates than that and wouldn't recommend it, was horrible.

Poofta...........

I think 150/75 might be a tad harsh bu I think Alex has them fitted!
