Sorry. How about: "You'd be crazy to sell your lovely coupe but at least you'd get a good price for the wheels."
Standard shocks with the Eibachs is pretty good - probably more comfortable than you have now. Talking of wheels, the lower profile tyres won't be helping matters...
I'll try standard shocks next. I thought the same about the wheels, but to be honest I couldn't tell much of a difference in ride quality when I put the standard 16s on while getting the 18s refurbished.
Just fitted some Fiat Recaros from Joe and the difference they make to the ride is astonishing. Seriously zak, don't sell the car or change the setup, get some recaro seats. Makes it feel like a modern car.
I already have the Recaros (air-bag type) as it's a Plus.
