what is the ID of bilstein pss14 front springs?

kasra340i · 10-26-2021, 04:05 AM

I'm trying to order GC Camber plates to pair with my bilstein pss14 but can't find the ID of the front springs anywhere. Does anyone by chance know?

You need the OE spring perch. Bilstein B14/16 coilovers have a 60mm ID bottom and stock spring (~96mm IIRC) ID top.

If you are ordering the camber plates anyway, you could get the 2.5" spring perch, 2.5" Hyperco or Swift Springs (in a 250-275# range) and get 60mm to 2.5" adaptor plates for the bottom. 2.5" springs fit over the Bilstein dust boots better than 60mm. This also leaves you room to experiment with different spring rates if you want to work on getting tuned for Flat Ride Suspension. my 0.02

I have the B14 kit and got Vorshlag camber plates and this is what I ended up doing. The B14 kit comes with 400# front spring rate. Too stiff IMHO and according to many who have installed the B14 kit.

(I also upped the rear spring to a 750# Hyperco)

Never even put the Bilstein springs on thanks to Farkle and his wisdom. That being said, I am extremely happy with the ride. I have my camber set to -2.9* for canyon carving and general spirited driving (yes I know my tires will wear faster). With the Bilstein\Custom setup, it is definitely a different animal than the factory M Sport suspension. With the camber plates, I have a lot more road noise, but I don't mind that.

The Verdict - Flat Ride is where its at. Do some research. Farkle on this board and Fat Cat Motorsports on YouTube. They explain it all in intricate detail.
