If it's a PS4S 295/30/20 for the rear, it will rub an insane amount on compression. There is nothing you can do to make that rear setup fit other than pulling your quarter panels or going wide body. I don't care what anyone says. Even if you don't care about rubbing, it'll look dumb at stock height. The rear wheel will poke out a lot while the front will be inset a bit. Looks like this set is coming from an E9X M3? |

Hi all!
I'm after some help nailing down exactly what offsets I need on KL01s for my F82 ZCP. Looking through the thread and wider forum there's lots of good info, but none of it fits what I want exactly and I'm getting confused! Included details of my plan and goals below - sorry about the essay, figured it was better to give more information than less to save questions. Hopefully all you clever people can assist me! Currently running stock 666M wheels and tyres (data below to save having to Google it) F 20x9 ET29 265/30 R20 R 20x10 ET40 285/30 R20 Goals: -CS style staggered setup, Michelin PS4S tyres, F 275/35 R 305/30 - wheels F 19x9.5in R 20x11in -Full clearance when lowered 15mm F and R with KW DDC in future - don't want to do any guard or fender mods. -May incorporate camber plates with the KW DDC but need clearance without either of these installed as wheels and suspension/camber will be done separately -Big brake kit clearance for future Brembo GT|BM 6 pot front 405mm, 4 pot rear 380mm -Ideally a small increase in track width F and R, but clearance is the priority. Note local regulations dictate a maximum of +/-25mm track change to maintain road legality, so a maximum change of +/-ET10 on stock is all I am comfortable doing Decided to go F 275/35 and R 305/30 rather than F 275/30 and R 305/25 as the overall diameters are closer to stock, so less speedo error factor. Also feel it's safer to be going faster with slightly larger diameter wheels (reduce BMW's ~6% speedo error to ~4% but still be under the limit) than going slower still with smaller diameter wheels and turning into a mobile chicane on the highway. As I want to increase track width and ensure the wider wheels fit in the arches, I need a more aggressive offset but have a maximum of going 10mm more aggressive to adhere to local laws. Which leaves me with: F 19x9.5 ET 19-29 275/35 R19 PS4S R 20x11 ET 30-40 305/30 R20 PS4S tonypgst at post #211 has my rear wheel and tyre setup but no mention of lowering/clearance I could find ratedlemon at post #209 has my wheel sizes and is running KW suspension but no mention of tyre sizes I could find AlterZgo, Mojoman and @x.shell seem to have sorted an aggressive, lowered setup on my wheel sizes but using different sized PS4S tyres at post #282 ellipsis212 also has a setup that could provide helpful info at post #235 I feel like there's (surprisingly) more wiggle room at the front for varying offset than there is at the back. Front offsets seem to vary wildly from ET17-ET29 whereas rear offsets seem to stall at ET37. Can anybody I've tagged above or any other knowledgeable person suggest what offset ranges would be safe for front and rear to fit my situation? Thanks heaps! |

Any issued on this set up for a M4 stock suspension. The seller has them on his m3 cs and says they only have a small front tire rub on full turn.
BC Forged Rims (Front: 19x9.5 +20 KLS02) (Rear: 20x11 +40 KLS02) Michelin Pilot Sport 4S tires (Front: 275/35 ZR19) (Rear: 305/30 ZR20) |

I had a look on Will They Fit and it looks like a 275/35/19 is only fractionally larger diameter than a 275/30/20 so that's a good start. Do you reckon a less aggressive offset would help the rubbing issue? I'd be perfectly happy running say ET22-24 on the front. What drop do you have on your KW? Quote:
Having spent much of the last few days looking through forums at this stuff, I've found that the F82 apparently has better clearances under the front guard than the F80 so if it rubs on his M3 CS there is a chance you have have no rub on an M4. Have no idea if that will actually be the case though! |

Same here. Would love to see wheels w/ bright clear and stone finish. Wondering if bright clear is similar to polished clear or what the difference is and if a rim w/ bright clear face and polished clear lip would work.

Saw this new BC Forged wheel on the bc forged japan facebook page. Does anybody know what model this rim is? Reminds me of the Anrky S3-X4 but I assume would be 1/2 the price or maybe even 1/3 as Anrky/HRE have lost their minds on pricing.
