Rebound and bump for idiots

[shimmy]

And herein lies a flaw in that point: OEM suspensions are built with compromise always in mind between sporty handling characteristics and ride comfort...

I didn't fit KW Clubsports to emulate OEM road ride comfort after all! But if i'm honest they really aren't that indifferent to that now anyway when set up for road.

not sure what you are trying to prove Rob. the original poster just asked how he can make his car more comfortable when 'cruising' and refitting OEM is what suggested.



The OEM may be a compromise but in my opinion it is a much better compromise than Intrax or KWV3 for road/ring/track even with the adjustment. You cna bet your last dollar that more money was spent on designing it and setting it up than any of our a/m versions.

I tend now to favour the track use hence the Intrax but if my car was doing 14k miles a year again on road i would have no hesitation in getting the BMW suspension back on

Not trying to prove anything Shim - i was just countering your habit of answering peoples questions with a simple one line/word answer that doesn't always consider the bigger picture or take other implications into account.

He has KW V3 (by the sounds of it) and he may not have OEM anymore? So potentially not a simple or cheap swap back...

If you want mega comfort, then you could also consider KW V1 or Bilstein/ other aftermarket ride comfort biased offerings. I'm pretty sure that he doesn't want a floaty/wafty big Merc type of ride though...

Glendog74 - with a statement like that you are going to have to share your ride height and camber/toe settings:thumbs:

All set-up i.a.w. standard KW settings for fitting:

Not sure what toe settings were put on but my front camber is set to -2.5deg with ability to increase to -3.5deg if needed without any geo adjustments.

[shimmy]

i wish i ran -3.5 on track Rob, but dont you find that your inner road tyre wear with -2.5 camber is quite heavy?

i would be interested to find out what you front toe is with -2.5 and -3.5, castor as well:thumbs:

[daniel_csl]

Wow, its all kicking off in here. :whistle:

I don't want to go as soft as the OEM suspension, just wanted to understand how to create a slightly softer ride for long motorway drives. Think I now have an understand of what I need to be playing with.

Glendog74 - Thanks for the link.

Shim, I run -2.5 all the time on road with adjustment to -3.5 for track. No inner tyre wear issues at all. Ask Julian/Ant what toe and castor settings are because I haven't a clue.

I'm not sure yet!

Bearing in mind that i use a different set of wheels/tyres on road and track, i previously ran -1.5deg road and -2.5deg track; i found very slight outer wear issues on my road PS2 tyres (probably due to 'occasional' track use of my road set), and distinct outer wear on my track tyres - indicating not enough negative camber. My front PSC tyres have been written off prematurely due to severe wear with banding showing on the outside edges, whereas the centre/inner part of tyre has loads of tread left... :banghead:

Now that i have extra camber dialled in, i am happy to accept some additional road tyre wear - the track set should now wear evenly. If it gets that bad on road, i can always downgrade my road rubber to the 'cheapskate tyre of choice' - hard Falkens... Track is where i want my rubber to perform to its best ability :whistle:

I have Intrax 4-ways fitted, and drive everywhere with whatever settings Andy Mulholland dialled in, as Im too confused to touch it, and Im an engineer ! seemed to get him around the ring fairly quickly though !
imho im way too new to the car and track days,Ring etc. to even contemplate making adjustments, without any kind of benchmark, changes in setup would be futile in my case, all i know is that its gets around Spa in the wet, and the Ring, and it was pretty good around Bedford this week-end. It is I admit a bit harsh on the road but I have a large a$$ built for comfort. It would be nice in the future though to understand all about setup and how it can improve or otherwise my driving experince, but for now its foot down and hang on im afraid. I will however watch out for inner edge tyre wear as people have commented on the amount of camber Im running.

[TANKSLAPPER]

Duncan, don't you start ! ! ! !

LOL

[DuncanR]

T$ as my mentor with all things CSL at the mo, im like a sponge for knowledge ! ... and no i dont want to swap you my Intrax system for your very reasonably priced refurbed Bilstiens !!:hahaha:

i could have hours of fun playing with your 4 way Duncan!!!

Hi Glendog74 I would be really interested to know what castor and toe settings are linked to the -2.5 & -3.5 negative camber and how it changes if at all when moved to -3.5. Also do you know how they set the back up?? Camber & toe?? I'm quite shocked other people are running as much as -2.5 negative with no premature tyre wear inside on the road. Sorry for all the questions but I'm fairly new to CSL ownership and have adjustable topmounts now so would like the best of both worlds on road and track......:thumbs:
