Are you gonna keep those views to yourself Karl or an I gonna have to hunt her down?
Personally if I would go for Coilovers as the drop will be greater on a GT and hopefully improved handling, if it was an RS I would go springs as RenaultSport tend to know what they are doing
I had kw variant 1's on my 197 and they were awesome. Eliminated near enough all body roll, improved the stance and didn't compromise on ride comfort too much.
If you are going for just looks then coil overs are over kill imo.
If you want coilovers then get AP's, they're £515 which is probably the cheapest option for the GT in comparison to KW, Weitec etc. and they're made by the same company. I'm using them on my GT and I can't fault them.
Id reccommend springs for now, if its for the look, As others above have said Kam Racing is your best bet, they have a choise ranging in how low you want to go.
I woulnt say they're overpriced at all. I can't find another car brand new that costs the same that feels as fun to drive. The suzuki comes close but just misses that little Something. The gt is cheaper but as a used bargain, rs' still come up as something of a missed gem by most.
