I am currently planning to upgrade the suspension on my Hartge H27. At the moment it has a mix of Hartge and M-Tec stuff and is too soft for the mostly Track work it is used for. Current options are LEDA or KW Varient 2. What I am interested in is:

1. Views on the two current selections?
2. Different alternatives?
3. Good garages / specialists I could use to fit this stuff and set it up?

Sorry forgot to mention Garage needs to be in the south of england

Have you considered H&R Coilovers? Ive been in a car with them on and it was superb.

Leda will not fit your car I think, but I might be wrong.

Fitting?......its not a hard job. There are loads of specialists who can set it up for you. Where are you based?
