Coilover wheel clearance?
If you switch to coilovers do you have more clearance on the front between the strut/spring and the wheel than you did on the stock setup. If anyone has done this and is still running stock wheels and tire sizes, can you give us an idea how much clearance there is between the inside of the tire and the coilover?

Member 'Fair' (of Vorshlag) has answered this best, but I can't find his post. Basically, you need to make sure the coilover springs are short enough to keep the adjustment collar above the tire like the OE spring setup. I don't think KW v2 or v3 do that, so clearance is less than OE.

We have close to an 1" clearance on the inside wheel on our KW Clubsport. We are also running fairly high camber (we have camber plates). Be careful if you are spacing your offset inwards. The wheel well is small and you must consider clearance when you turn the wheel. Our offset puts our wheel very close to where the inside of the OEM wheel is and we only have 1/8" inch of clearance from the wheel well at full lock.

Thanks Fred. So the KW Clubsport has the clearance and I may be wrong about the v2 and v3. Someone with one of those installed want to take a picture?

On our particular setup (KW V3), the spring perch is above the tire. So you have the same strut clearance with the stock or KW coilover.
But it's not much to clearance to begin with. |

The OEM strut actually has great tire clearance. As MikeO has stated, you have to make sure that the spring package from an aftermarket coilover is compact enough to fit above the tire. I took these pictures recently...
That's a 135 with an 18x9" wheel, 255mm tire, our camber plates (which maxed out at -3.1° camber with the stock springs/ride height), and the OEM struts. I keep hearing how you can't fit big wheels on a 1 series... |

If you are refering to me Prof, then yes, my KW Clubsport is here, but no, the wider wheels won't be here for a bit yet due to supplier delays...

I had a chance to look at Professor's car that was on a hoist today. There really isn't much clearance between the inside tyre and the suspension. Prof has 225 front tyres with BMW Performance wheels.

I have KW Clubsport on my 130i hatchback and have 225/40/18 in the front (Michelin Pilot Sport Cup semislick tyres which are often wider than the declared size). This combo forced me to remove the upper spring helper.... ** BEFORE ** ** AFTER ** This enabled me to keep the adjustment collar above the tire, otherwise the collar was way too close to the tyres (5mm cleareance which is way too little and too dangerous). This bit was removed: If i want to put it back i will need to use 10mm (at least) spacer in the front. The original OEM tyres for the front on my car where 205/50R18 (Goodyear runflats iirc), so compared to the generous 225/40/18 of the Michelin Pilot Sport Cup we are talking about between 25 and 30mm difference (huge diff.). The original M wheels were 18x7,5JJ ET47. The OZ are 18x8 ET40. I do not get any "upper" rubbing though. Is anyone using same size semislick tyres on their car with adjustable coilovers? I'd like to hear some comments from Racewerks... Here is how my car looks: Bye, Carlo

Personally, I think 5mm clearance between wheel/tire and strut/coilover is just fine. I've run less than that with no issues.

Cool! I will try to put them back then or maybe use some 5mm spacers...
@WAY: can i ask you something !? This is a pic of my KW Clubsport kit before it went on the car: Please take a look at these (rear spring adjusters): They did not fit right on my car for some reason.... http://www.giacomino.biz/zsan/130i/problem.mp4 In order to fit them i had to grind out 4/5mm of its diameter as seen here: http://www.giacomino.biz/zsan/130i/solution.mp4 Did you have the same problem? Or were they plug & play? Do you have a picture of yours before they went on the car? Let me know :wink: Thanks, Carlo PS - Do you have 3 degrees camber on both front/rear ??

In this picture posted by Autowerks (see the "Big Brembo Brakes kit topic) it seems like they also removed the spring helper... Am I wrong?
Let me know. Carlo

Hello Carlo, beautiful hatchback!
About your spring perch issue, they should fit right into the frame rail cut-out of the chassis. You need to completely remove the OEM spring perch. From your video it looks like you still have the OEM perch in there. Take a look at our 135i coupe. The V3's and the Clubsports use the same rear spring perches I believe. Here's the rear of our car. |

I looked at your 1st video and yes, you did not remove the OEM spring perch completely. That black perch you are trying to put the KW spring perch into, needs to be removed. Parts number 9 & 10 in the diagram. |
