What size rims? (This is why the center of rim to arch is better - b/c then rim size doesn't matter). So is the entire suspension new w/ 7,000 miles or just the top hat upper mounts?

It appears my car sits pretty level. I'll try to get a measurement from around the jack points to the ground later. As pointed out earlier, much of the front to back variance is the wheel well shape. The OE ride heights have 8mm diff front > back while my car has 12mm so I have 4mm more squat or 4mm less rake than OE. (Terminology assumption - rake is tail up, squat is tail down) If your subframe inserts do add rear height, and you take away the effect of say 3/8" (~10mm) , you are at 578 front, 573 rear. A difference much closer to the spec diff. Then consider how much front strut mounts can compress your car gets into squat territory. N.B. I have 17" wheels so the absolute numbers will not be a valid comparison to your measurements. So you pointing out the front to back differences is pertinent. My springs and dampers have ~17,000 miles on them.

BTW, the stock measurements are "higher" in the front because the front wheel well openings are larger, as the front wheel have to turn. It is not actually higher.
More accurate to measure rake at the jack points. Last edited by MightyMouseTech; 03-19-2018 at 10:57 AM.. |

Do you guys measure to the side skirt just in front of the front jack point and just behind the rear? Or to the jack block itself? I'll see if I can find time to measure it later today. My driveway isn't flat so I have to go for a drive. Oh darn!

So is there anyone else out there that can measure their wheel gap front and rear on a stock 2011+ 135I?

mine is a 128 and convertible non sport. I know you needed a 135 but it's data from another stock e8x so maybe useful.
corroborating other people's results the front has a larger gap. front 36.5 cm center to arch rear 36 cm center to arch like somebody in the forum said: "monster truck" EDIT: corrected units from inches to cm. |

I measured my 135i M Sport using the bottom of wheel to bottom of arch.
Mine has 18" wheels and has done 164,000 km (102,000 miles) and I got almost the exact same result as Gangplank. Front 580 mm Rear 585 mm It looks like these cars sag at the front and I reckon mine should be lifted about 10 mm at the front to be right. I'm getting coilovers fitted next week as all my bump stops are split, smashed or gone. I'll get the experts there to investigate further as I want to keep close to factory ride height. |

2008 128i Koni Sports and 135 springs. 10,000 miles on new hardware. Center of roundel to front fender 14.5" or about 368 mm.
Either the 135 springs did nothing, or Enoe's car sagged about an inch from the worn out bushing i mentioned in another thread. https://www.1addicts.com/forums/album.php?albumid=15081 https://www.1addicts.com/forums/show....php?t=1436998

Update on mine: Just collected the car and drove home in peak traffic so didn't get much of a chance to check it out. However, the ride feels comfy and, on the freeway exit near home that I normally zip around in a "spirited driving" fashion, the car just sat flat and felt superbly planted. Ride height data on the set-up sheet given to me, shows suggested ride height 322 mm front and rear, measured from wheel centre to fender arch lip. However, although it is certainly sitting higher than that, it does have some rake (nose down attitude). Springs are 200mm 6kg front and 200mm 11kg rear. I'll take some actual figures and pics after a test drive over the hills on the weekend. Last edited by JBT2; 07-19-2018 at 06:20 PM.. |

The difference between 17" & 18" Radius is one constant value 12mm. 582mm would be the logical correct value, no? For information on my 125i (same as 128i) with Perfo Springs (Lighter ones) i have mesasured it to 580mm in Front axle. Thanks |
