Rear bush limiting kit + wheel spacers

[cslbecks]

Yes, ive heard it can wear the front tyres heavily - but it does look bloody awsome imo!!
In terms of the limiter kit - im slightly confused - what is the point and/or benefit of fitting the limiter "kit" as opposed to just having say powerflex bushes fitted?? Dont they do the same thing or do you get something extra with the kit??

I run polly bushes and they cost under £40 thats a bargin
and make the car feel alot more planted

[cslbecks]

Ok - but then what is the point of fitting the limiter kit when it costs a lot more? There must be a benefit in fitting the kit as opposed to just fitting the bushes surely?? Otherwise everyone would just fit the bushes. Help??

The limiter Kit looks to me like 2 washers to limit the play in the standard bush. witch are crap thats why i fitted polly bushes.

I am sure some 1 will have a differant opinion

Yep!

According to Simpson Motorsport, they seem to think the CSL bushes are actually ok as they are an uprated version of the standard M3's which weren't good...

The limiter is indeed 2 big aluminium washers that is designed to reduce the free space either side of the bush housing after BMW fitted a housing bracket with a little too much scope for lateral movement! In either case, the end result of a limiter kit and/or poly bushes is broadly similar...

Simpson don't really recommend poly bushes for cars used mainly on road as they can wear prematurely (compared to rubber items) and also transmit vibration more readily to other suspension components as well as making the ride harsher. The limiter kit is more expensive but in the long run, maybe needing to swap out poly bushes and worn kit would be more so?

If i had enough spare cash to just use my car on track as well as owning another daily driver that made me smile like the CSL, then i might consider poly bushes, but i have the issue of covering relatively high mileage in my CSL with the occaisional track day and i would rather not put any undue stress on suspension components.

As it is, the limiter kit has certainly worked to make my car feel noticibly more stable in high speed corners during my latest visit to the Ring. I recommend it...

Agree Glendog, was told the same today.Poly's don't last as long. Was aLso told that with the Limiter kit there is no movement at all in the back......so my question is how does it affect the ride in the back. If you are using the car on the track often then this makes sense but surely for road use then the standard set up is OK?

Nice one!

I personally think the LK is one of the best (price vs effectiveness) mods you can do to a standard CSL. You can feel it immediately and is cheap as chips.
Unlike all these remaps and exhaust type things.

If the limiter kit stops it moving why has bmw not done it ??

It needs to move thats what the polly bushes do but are not prone to falling
to bits

Thats what I was thinking to be honest Mark. The rear of my car seems well planted without to be honest. As I mentioned if you area track junky then it may make sense but for everyday is it needed.

I suppose it all boils down to being a handling compromise between a stripped out road racer and a 'luxury cruiser' - of sorts! I tend to prefer the car on the racier side.

Oh and cost, and the fact that BMW wouldn't want to admit being wrong!
