BMW 3 Seies E90 E92 RWD Coilover Suspension

Free upgrade to the S3 with adjustable camber plate & pillow ball mount.

The S3 suspension system has an enhanced forged front pillow-ball top mount to increase steering response. This suspension system is perfect for daily driving, while having the adjustment for track setup. 

Each application has a specific number of adjustments. To increase rigidity, you turn clockwise, whereas to decrease rigidity, you turn counter-clockwise. Set your handling and ride as comfortably as you like.

Our full-length adjustment system by the lower mount allows separate ride height and spring pre-load adjustments to increase performance while keeping the comfort. You can decide your desired height first, without affecting the spring pre-load, and afterwards you can set the pre-load.

And the gents over at Sonic Tuning have been awesome thus far. Had a tracking # about an 30-60 mins after I sent the payment info, and they're quick to respond to emails. Hopefully the product lives up to the customer service so far.
