I thought I would pass this along to the 5th Gen folks who are looking for custom coilovers.

For 2010, we are running BC Racing coilovers on the SER. These have proven to be the best coilover for track/street use. They are fully customizable to your exact spring and damping specs, so you arent stuck with out of the box damping that doesnt work on the track. You can also order additional spring rates. Each shock dampening is set up +- 2K for springs. So if you choose a 8K spring and dampening rate, you can go as high as a 10K spring and as low as 6K with the perfect dampening rate. Its the perfect set up for drag and road racing.

5th Gen Specs:
For limited street/hard track competition - 10K Front / 11K Rear

For street/moderate track competition - 9K front / 9K Rear

For balanced street/track use - 8K Front / 7K Rear

For drag racing - 9K front / 12K Rear moderate 10K / 14K Ultimate

$1050 Shipped. Each additional spring pair is just $90 shipped.
Inverted Front Shocks, add $200 < Super Trick

Order a set between now and April 1st and receive a free pair of springs, any rate you choose.











Specs:
The BCs use 46mm pistons and 53mm shock housings, the enlarged shock cartridges with specially designed pistons and rods provide a wide range of damping force.
- Valves are constructed of special spring steel, which outperforms stainless steels and produces longer valve life. Valve stacks use a patented deflective system to provide more precise control.
- Patented concave lower locking ring, to prevent unseating.
- Springs are made of SAE9254 high strength, durable steel. Compression tested at over 500,000 tires with less than 5% deformation.
- T6061 Aluminum utilized in spring locks and seats for high strength and lightweight.
- Iron lower brackets on MacPherson struts to ensure rigidity.
- Piston rods are constructed of highly polished steel to lengthen oil seal life and prevent leaking.
- High pressure inner rod guide seals ensure a perfect fit for consistent fade resistant damping and long shock life.
- 2 step coating process utilizing nickel and chromium plating to prevent corrosion.
- Newly developed lubricant oil in shock cartridges minimizes aeration and cavitation.
- An additional bearing beneath each pillowball mount provides the smoothest action and prolongs the lifetime of the pillowball itself.
