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

[nick///M3]

Me too, hopefully :whistle:
BTW didn't the LOADED CSL run Ohlins suspension ? :smt017

first i think i was on kw's and later on some very special bilstein's....at least that was the info on their website..

lighter engine componets
full exhaust
wheels
brakes
seats
the number came up on the scale where the car was corner balanced.

still to go is the roof 28kg's and the back of the rear seat 11kg's...

can't get rid of the insulation or the windows...

and the number for the csl that you gave me is with a driver...( if you can a 68kg a driver!!!:hahaha: )

sorry did not "catch" the joke...

Last but not least, I will be able to provide some feedback next year about my favourite Ohlins suspension :whistle:

Different car (evo), but I did the "what suspension?" thing to death this year. Looked (hard) at Nitron, KW, Exe-tc, Ohlins etc. In the end I went for KW competition 3-way (pricey!)

Now I'm about to do the suspension on my CSL.

What I can tell you that I've learnt along the way...

1. Unless you are a suspension guru, stick to a single adjuster setup !
2. Ideally, top-adjusters are best to save scrabbling around underneath the car
3. Consider carefully the after-sales service you will get. If you need advice on fitting/setup, is your supplier available on the phone and speaks the same language (the real KW setup guy is German, has good english but its not the same...) Also when it comes to needing them serviced/repaired, how easy/costly is that going to be?
4. If you've an off-the-shelf kinda car, buy an off-the-shelf package
5. Choose a vendor with a proven experience in your car, not just x years in the suspension industry - all cars are different.


For what its worth, for my CSL I'm going with intrax 1k2 from simpson. My next choice would have been KW Clubsports. If KW had a decent (fitting/setup) outfit in the UK I might have gone for them, but their UK arm is just a box-shift job.

HTH !

cheers
Lee.

my car weights at 1490kg with 1/2 tank of gas in it...
i think it's quite good and there is some more to be saved in the very near future...around 40kg more with my poor estimates...

sorry did not understand the pic..care to be more clear?

Just a little joke :hahaha: nothing serious.
What I'm not sure about though is how you're getting your regular "PHAT" M3 down to these weights :smt017 when a GENUINE M3 CSL (without any options, so: no A/C, no CD player, no Xenons or PDC or even Comfort screen) is 1460 kg with 90% fuel, 68 kg driver and 7kg luggage... or 75 kg driver without luggage :whistle:

one thing for the suspension is to be stiff and firm and it is another thing for the suspension to give you the idea of constantly bottoming out and be harsh on its reactions and only performing good on flat roads or the track...if you go over a road anomaly or a potholr with a GOOD suspension to absorb the beating right is it going to be the same thing with a so n so susp? no!

This is what is happening 99% of the time when someone puts a 'race' suspension to use it on the road.
It is better in one area, and worse in another 9 areas.
That's exactly why shimmy said earlier that the OEM suspension is the best thing for the road.
That's also the reason why I personally didn't change my suspension. Most of my kilometers are on the road (Swiss road which is better quality than many racetracks).

Also, my opinion is that if someone doesn't understand what the car is doing, it's better to stay away from adjustable suspension. You don't need any suspension wizards to tune the suspension if you understand what the car is doing and what you need to change.
Now don't get me wrong about this, that I am saying something between the lines. Quite the opposite, I am saying this in general because I have seen many guys with a super-duper suspension and have no clue about suspension settings/behavior whatsoever.

Last but not least, I will be able to provide some feedback next year about my favourite Ohlins suspension :whistle:

So basically you don't want the car to be hard neither you want a track oriented setup.
Road and track suspension kits tend to be a bit hard for road use.
Also take into account that your car is significantly heavier than a CSL and the suspension that works well in a CSL won't work in your M3.

i did not ask a velvet carpet to put my car on it....

i asked opinions based on experience for 2-3 specific set up's that have my attention... and the people here have this experience...

some more input and i think i am convinced...

Could this be the solution ?

I am not going to the track so often but i want something good either way..

I want the car to behave like an M3 but firmer more stable...
When hitting a pothole i don't want to feel like the suspension is bottomed out...
Neither to feel the car hard, bumpy or crashy

Moton has a streetsport kit and I think JRZ does as well.

i was thinking about AST as well but changed my mind for the same reasons plus the fact that some guys had some fitting problems so....

where can i find a quote for the intrax suspension???

it seems to be very popular here....!!!

I run Nitrons & IMO work great on track. Makes damping adjustment a doddle being in the engine bay. Not having to lay on your back & crawl under the car with a wee allen key or similar is a big plus. Little hard on road as I have uprated springs, but all the better for what the car is used for. PM moi if you need any more details, I can put you in touch with someone if wanting to go that route. Good Luck. :thumbs:

Nick, you may want to take a look at ASTs as well. They're a monotube shock. Works very well at the track, which is what I primarily use it for, but also stock like comfort for street use.

This will give Nick a headache ... 3 options ! ..... Intrax for me here :thumbs:
