Hi mate,
That was my thought, I'm not spending over £1000 on suspension for a car that I bought for £2000. In the end I went for the tein street basis z which were £500, but has been the mod that has been the most worth it so far. I wanted to drop it quite a lot but the ride is still alright, not perfect but never expected it to be, and wasn't too much of a pain to install. Love your car though, that kit is gorgeous I wish they weren't so expensive otherwise I'd definitely have one.
