rear wheels on the front
 

quick question

is anyone running csl rear rims on the front?

what are the pro's and con's?

any advice would be great:thumbs:

AlexGTT;):thumbs:

due to the offset you have to run -3 camber to avoid arch rubbin.

on track ok but on road tramlines like a bugger

Pretty much as Shimmy said. I loved it on track but was a bit of a pig on road. With the right set up the front end is absolutely nailed on but only worth doing in warm/dry conditions and tracks where you need a good front end. I don't mind running the setup for a quick road run to a track but for touring forget it. Best way to do square set up is with 18" wheels and the right off set. It's a bit easier on road then as you can run slightly less extreme camber. Ask Shimmy about that.

I only run it occasionally to get rid of my 265 Cup mountain of part worn tyres.

rears on the front
 

brett,shim and alex

thanks for the advice

currently running -3 camber with 235's and 15mm spacers

this pm i fitted a worn set of rears to the front and will give it a go

loving the deep wheel look on the front!!

Pictures - or it didn't happen ;).

cslsuperfan - as they say, wheel rub is problem, and defo if you were tracking it fast in a compression.
Im running square set up on 18" TD's, and found -3 a bit too much, and rubbed inside tyre edges out too quick, I run -2.5 and get a more even tyre wear.

"it happened!!"

WOW - that's one filled wheel arch!
...edit yeah I know two...

Very purposeful :)

square set up verdict so far
 

80 mile test drive today.

no rubbing on front arches on road test

car clatters a little more over poor road surfaces(30 profile doesn't seem to affect speedo accuracy.. 80mph @ 3000 rpm which is what it was before running 235's on the front)

tramlining is interesting!!

turn in is sharp!!! cesil behaved well but the tramlining keeps you honest and both hands definitely on the wheel

i'll bring both front wheels on the munich trip just incase i have a change of heart:-D

What neg you running?

I run mine at -3.3 with even wear on last set of cups on 18's and last set of GY's on 19's.

I dont mind it tram lining on country roads as used to it now.

But do swap rims round each TD.

I have recently tried an 18x 9.5J ET25 up front and found no issues of yet. Tiny rub on plastic wheel liner on full lock.

18" is the better option in my opinion but std 19" do make the car look hard as hell!

Oh, and forget the spacers on front with rears.

Lovely :).

Could you (both) post up some side on and ¾ angle pictures showing both the front and rears together :)?

This sort of angle:

Looks like a great set-up Ben, for reversing (Rear wheels on the front)? :hahaha:
If it was the optimum set-up don't you think BMW would have adopted it and just used one wheel size, would make commercial sense if nothing else? :)

totally agree neil,
i'm famous for messing about with the perfect set up.....
"no idea with some of the gear!"
if i'm honest the car felt better to drive with standard fronts and 15mm spacers but as billy's csl beautifully illustrates...it looks f...ing lovely and agressive and i'm going to persist with the square set up in the hope that i will adjust to the feel of the car's behaviour...

Mike R,
now i've sussed pic upload
i'll drag the car out on the next dry day and snap away

mine's no match for billy's csl in the picture department, i first saw billy's csl @ elms meet in oct 2011...well i heard it first about half a mile from elms on approach!!!
It really is a sound to behold....

I'll guarantee you Ben the Tram lining will eventually P**S you off good & proper on our pot hole ridden roads. Yes ! it looks great but...
I run a square 19" rears all round (albeit) E46 M3 19" rears which are the same size & off set as the CSL rears but a little heavier. It lasted less than 8 months and I'm now back to OEM 19" CSL set up with full PHAT CUPs and 12 mm H&R spacers @ the front + 10 mm H&R spacers @ the back. For me this combination is sweet as a nut :supz:

Matt,
thanks for your take on all things square
your cesil looks mint with the black wheels....front end looks even sharper with the black rims....oh christ! i've now got a spare set of rims so post munich i'll refurb in black....your bbk really stands out...loving it!!:thumbs:

Oh No !!! Look what I've done now !!! :hahaha: Oh well ... here's a few more pix for Satin Black wheel inspiration :thumbs:
Yeah the Red BREMBO BBK really stood out against the black wheel but I just prefer the "Sleeper" OEM look with cheeky spacers :supz:

Neil define 'optimum' :wink: it all depends on your priorities :beer:





I would drive on the front wheels, and bring the rears for the ring and the salzburgring.....
then you will look tough on track where it counts and won't wear your inner edges on the million mile motorway journey:beer:

That's the most sensible thing you've said in a while Jim :wink: :hahaha:... U feeling OK mate ? :goodman: ;)

:hahaha::bigcry::birdman:


I do have the odd moment of clarity Matt :smokin:

Fortunately (for us) it's only momentary :wink: :hahaha:

That's what I do now Jim. Also well covered for any puncture issues on the road, front or rear. :wink:

point taken jim,

rears in the boot on route :-D

'Optimum' The best or most favorable condition, the greatest amount or degree possible under specific sets of comparable circumstances, you had to ask Jimbo :hahaha:

My understanding is that the CSL was developed on a track, specifically the 'Ring', however as most normal roads bare little or no resemblance to that, what we have is a compromise in the interests of general usability. :thumbs:

Ben,

What was your outcome in the end?

Do you run 19" rears all round all the time or only on special occasions? :wink:

Rob

Rob,

I have run rears all round since simpsons altered my front camber.... no inner arch rub but it still tramlines like a bitch on any worn road surface.

15mm spacers with oem fronts are the best compromise as the tramlining can snatch the wheel if you're noddying.....:smokin:

Cool - cheers mate :beer:

Id go for it, I prefer driving it with no spacers at the front and -3.30 camber.

Yeah - that's what i'm now gonna do. Probably gonna sell my BBS wheels as i prefer the look of 19" sets.

Im going to get mine back to standard colour then stick some new cups on.

Ben you got any pictures?

Post 8 on this thread ...a few pics of rears on the front;)

Any updated photos by anyone ?
To show better the whole car with the square setup :thumbs:

Sorry to bring an old thread back up from the dead, but does a square setup and the aggressive camber people spoke about (3 degrees or more) require aftermarket top mounts etc.?
