Lou,
I've got the G-max full kit on mine, i managed to get it second hand with only low mileage on'em. Even new the kit (4x uprated dampers & 4x -35mm springs) is circa £180.00ish.
I'm hopefully going to get better stuff in the new year, but for the time being they seem to be upto the job......seeing as i drive everywhere like a man posessed!!
Guzzler has given me a good price on the full car set of powerflex bushes, a must i think if you are doing ya suspension.....just think, ya original bushes are 15 years or so old now
You can get Eibach springs from Elites in Rainham and ya Konis from Mr Rainbird prob
For about £300 or so, you can get ya car poly bushed and sitting on new suspension
