Hi if you wanted a good used set of Koni's and springs i have just replaced mine with Gaz Gold coilovers on my 3dr. My springs are Ahmed (RIP) 3dr specific in the track spec but work very well on the road in my opinion. I bought directly from him at grove several years ago.
I haven't been able to drive it far yet on the Golds (in and out of the garage but had a problem) as converting to 6 degree rear beam and waiting on Anembo to do some work on my trailing arms.
I think the Golds will deliver better damping control and i wanted a bit more adjustability hence the change.
what wheels do you have that are causing the rubbing issues?
i think a nice low ride height on the original 15's with 10mm spacers at the back really suits it.
On the other hand i know how you feel I trimmed my arches a few years back to squeeze my comp CXN's on.
