SUSPENSION CHOICE KW or NITRON...!!! (heeelp )

[s.mac]

AST non rear coil over is working well for me, but if it's not for track OEM can't be faulted

What benefit's does the KW Clubsport/Intrax 1K2 etc kit actually give over OEM suspension?

Is it just a case that body roll is reduced or can you genuinely feel the improved bump/rebound etc in the kit/strut?

Depends where you are driving and what geo one is running

My guess thru trying both I'd that on A& B roads in UK the OEM will give you a better ride, better grip.

Face facts in that BMW built the suspension to run the ring as fast as possible. I personally doubt on road Tyres and geo a/m suspension will be any better.

Yeah sure, but what about if it had 90% fuel and you in it ? :whistle:

Well matt i would say with a full tank and me 1545kgs carn't be certain till i get down to ikea and get new scales

Where did you get hold of the 3 - Way KW kit ?

custom built by KW in germany and shipped to me...

I assume the german KW dude you were referring too is Mitch ?

Michael Grassl.

I can highly recommend AMD in Essex

Cheers, might give them a try. Yes, Raeder Motorsport got a look in too :-)

You mention AMD and Thorney, but are we talking M3/CSL here ?

Essentially my evo is akin to a prototype with regards the amount of knowledge out there. Custom this and custom that, nothing with a mitsi badge on it anymore.....



The kit was built to a spec designed by Michael taking into account overall weight, front/rear split, tyre sizes and compound, intended use etc.

Interestingly their recommended settings are damn good. From that point if I soften it up I lose high speed stability and stiffening it reduces traction. Textbook stuff.

Certain tuners/companies know certain cars. Nitron are massive in lotus circles, not so much on evo...KW were one of the few who have actually had experience of racing the damn things :-)

Comp 3-ways are not for the wallet conscious though !

I'd like to disagree with that statement please :-)

Car manufacturers face an almost impossible task with regards to the performance aspect. They have to consider a great many factors that aftermarket do not.

1. Will these uprated parts last ie avoid warranty issues...
2. Parts have to be put through various approval processes for domestic market (check a lot of aftermarket parts, they mention track or off-road, not street legal necessarily...)
3. Parts need to be made in reasonable quantity and speed. Hand-assembled might not be the way forwards and costs need to be kept down.
4. Parts need to be put through stringent testing for safety purposes etc
5. Parts need to be designed for minimal maintenance and quite possibly some neglect.

When you buy a suspension kit aimed at track use you don't get much of a warranty to be honest. If a coilover broke and you lost your car into the armco good luck pursuing that claim. If your coilovers need rebuilding every 2 years, that goes with the territory. Expect to have to keep them far cleaner than a daily shitter etc.

All I'm saying is that in general it is a mission for oem to produce something that is totally focussed, its always a compromise.

I have an internal training document for the Porsche GT2 RS. When you read through some of the stuff they do on these cars, you look at the build quality and attention to detail its just amazing. End result, sell a lung to buy one. You're not buying £165 of tin, you're contributing £100k+ to the entire R&D project that got you there.

[Thorney]

We now only use Moton on all our cars, CSL Cup, E92 GT3, Gallardo. We offer Nitron as well on the Csl as a cheaper alternative. Whilst there is an element of sponsorship from Moton on the race cars we pay for all of it. We've not needed to rebuild any Moton shock in three years.

Which bit are you disagreeing with? You see to be talking about something else!

On a proper track on a road car a/m suspension has a little scope for improving speed BUT on the Ring I stand by my statement OEM suspension will be as good.

I've not seen anybody beat the official 7m50 full lap time of a CSL which wa set on OEM

Coz were not professional race drivers who drive the Ring for a living :bigcry:

I'm with Shimmy on this one :smt023 ... even a well used O.E.M. CSL suspension works a treat around the Green Hell (aka The Ring) :whistle: ... not too cleaver around Spa though :bigcry:

[mattCSLnut]

... in somebody else's cars :thumbs: plus we never get an empty RING to ourselves :bigcry: as much as we'd like to :hahaha:

[glendog74]

WHORE! :hahaha:

[mattCSLnut]

WHORE! :hahaha:

:smt003 I THANK You Sir :blalalala:

[nick///M3]

i haven't decided yet....

but the thing is, if the stock is so damn good why do people go on to change their suspensions?

doesn't a proper a/m suspension gives better handling and more firm ride than stock ?

a several thousand suspension offers what exactly?

besides talking away the 4wheel drive look ( bling matters for something..) what else is there??

It's called "wear & tear" :banghead: BMW Warranty only covers suspension parts up to 60 000 miles / 100 000 kms ... after that it's "BMW Good Will" but that rarely goes through on suspension components these days :bigcry:
The cost of replacement O.E. CSL suspension is almost the same as a decent after market suspension kits so most owners go for a/m suspension kits as it offers better adjustibility + in some cases the a/m kits can be rebuild after a few years use, unlike the O.E. stuff that just gets bind :smt087
BTW the O.E. CSL suspension is quite firm as standard, even with a few miles/kilometres on them :thumbs: and lower doesn't automatically mean better :whistle:
