Tire wear on lowered car
I have PSS10s on 06 325i ZSP, installed at 72k.
They sit way too low even though adjusted to max height. at 88k the rears are worn inside excessively due to 2 degree neg camber. Sadly its adjusted to min neg camber (!) which measures 1.9. Daily driver, never tracked. Front is OK since I have only very little negative camber. |

Not bad at all...my tire's wore great and improves cornering....with the M3 front bits I was at about 1.4 degrees camber and it is great. Befor this was also maxed out and tire wear was fine.

I would not recomend getting coil overs. The 1000's of levels of adjustment gives you lots of oportunity for getting the suspension wrong. Even race teams get it wrong. I did a lot of research into this and came up with the following options
Alpina D3 set up is good making use of SE, Msports and Alpina parts Hartge does a kit that is softer, but handles much better. They can let you drive a demonstrator to prove it Speak to Birds in Uxbridge Schnitzer does a kit and again they will have a test car. They guaranteed the kit when i spoke with them and would remove and give a full refund at their cost if i was not happy.Speak to Chris Rositer based in Norfolk BMW Performance kit has good reviews in the forums Koni does a magnetic damper kit KSD which gives a great ride and good handling and has good reviews As for costs the Koni is just dampers at around 600 + Fitting + alignment and would be the cheapest The alpina would require a bit of research and would be variable depening on which parts you already have. The Hartge and Schnitzer conversions where around the £1200-£1400 fitted for dampers, springs and fitting and alignment The BMW Performance kit can be procured on ebay and dealers for around £800 but then requires fitting and alignment. Out of interest my car is a 330ise and i find it skips at the back, understeers at the front. My feeling is the car has too much rebound damping at the rear and not enough at the front. However i found a very cheap way of improving the skipping. The extra weight of my golf clubs in the dealt with this to some degree. I have yet to change the suspension as it has slipped down the priority list due to having baby's. Last edited by sohlman; 01-12-2013 at 04:26 AM.. Reason: added bits |

Koni's make a great product. I have had BMW's for many years. I have in the past always looked at Bilsteins and eibach springs and this seems to work well with older BMW that were a bit soft and needed tightening up. However now i feel BMW's ride is so hard the tuners i spoke to are now making the suspension softer not harder. Koni's are the OE damper of choice for ferrari and are very relliable in my opinion.

Would Koni's & H&R Sports be a good option? (328 RWD Sport package car )?
Not looking for harsh just a tad lower and improved handling. ( same as OP )

The reason I asked for the height was, I think suspension height at chamber goes together. If it's extremely low, a lot of camber would be less effective troublesome than a lot of camber at stock height.
