does anyone know where I can get lowering springs from in the UK?

 

Since H&R springs are made in Germany (AFAIK), you should have no trouble getting them in Europe. Or I'm sure Dan at Mach V could ship you some from here (fastmini.com). Might not be cheap though.

 

They are $199 at tirerack. And If I remember right $229 at North American Motorsports

But because of the awesome support I highly recommend getting them from Alta. Alta's shipping prices seem to be lower than others too, which evens the playing field out a bit.

 

I picked up a set of Mach V springs from Fastmini.com. I believe they have a 10 year warranty which will be longer than I own the car. $199 delivered. Red, so they'll match my swaybar (Alta).

Both are progressive rate springs, and since nobody has numbers for what the rates are, I can only assume they're similar. I haven't heard any complaints about either brand, either in construction or operation.

It may not be readily noticeable, but the 1.25" drop of the Mach V's seems to be perfect for the R56 (at least in terms of the arch gap around the wheels).
