Helper Spring Question - Coliovers

[Coops Mk1]

I have FK coilovers that run 2.5" ID springs in 7" flavour. they also have 3" helper springs

I want to buy some higher lb springs for track use, so my question is what's my best option? leave the standard helpers in there and buy the 375lb I want in normal 7" fitment.

Or should I buy some say 9" springs and do away with the helpers? (guessing I wont need 7+3" as the new springs will compress less when fitted than the originals plus spongy ass helpers?)

any experience or advice much appreciated

cheers

Ben

I'd keep the helper springs and get some uprated 7" springs. Also are you certain they're not 60mm springs as I'm sure FK run 60mm like the rest of the Germans.

they could well be, where can I get them from? if they aint the usual 2.25 or 2.5?

Faulkner might do them. Otherwise Eibach, H&R, FK themselves

treid Faulkner, nothing on the website (planned on buying from there) but I may ring them

if not I'll have to bite the bullet and go European

You might find asking a company like coil springs in Sheffield to make some for you is cheaper than buying off the shelf Euro items.
