n00b question - hopefully I'm posting this in the right place and am not asking a question that's been asked a million times before!
I need some advice on springs if you don't mind. Here's the situation:
I recently bought a '97 328i Sport Coupe. It's lowered 40mm front and 30mm rear on the standard yellow Bilstein shocks. I replaced the rear tyres last week with Avon ZZ3s, which have a much squarer sidewall then the Bridgestone runflats that were on before, so now the tyres are scrubbing the arches under acceleration, cornering, over bumps etc.
I've looked into various options (increased negative camber, rolling the arches, fitting smaller wheels etc), but having realised that the rear springs are a bit knackered and need replacing, I might as well kill two birds with one stone and just increase the ride height a little.
I don't want to go to standard height as it'll probably look a bit 4x4-ish on the 18"s, so I was looking at something like this: http://www.demon-tweeks.co.uk/Perfor.../0/54065/24196
So, that's a very long-winded way of saying... will those springs fit my shocks, or are the Bilstein units wildly different dimensionally to the standard 328i units?
...or is there another (cheapish) solution that anyone can recommend?
Thanks! Here's the car in question:
