:sick: :sick: Thats ALOT. Whats the AST equivalent of the Clubsports? Do you know which AST kit is on the APR Golf?

Why?

....I haven't but I think it's a very valid and interesting point (and typical of Sy :grin:).
At what point does losing weight begin to effect suspension spring loadings?
Is one solution to have the car corner-weighted again?
Janner_Sy:
Because the spring rates are designed from the front/rear axle weights, so if you drop 100+kg from the car for instance and are in the market for the best suspension setup for £1xxx+ surely having a set of springs bespoke to your individual car makes sense, why pend all that money for something which isnt optimized for your car?
Edit
This is why the Octavia vRS, despite having an IDENTICAL under pinning, uses a different coilover kit to the Golf GTI. its dwn to the weight of the car.
An analogy for you:
Driving a lorry that is unloaded is ALOT more uncomfortable than when it is fully loaded because the springs havent got the weight applied o them to make them work efficiently.
This is the same as say a Golf GTI with an uprated suspension kit. Remove 100kg and the springs are then over rated, thus the ride gets worse and handling "potentially" worse, or at least limiting the potential improvement of the weight loss.

....Indeed, when VWR took advantage of their technical partnership with KW Germany, they ordered springs to suit my individual car.
Some folks have poo-poo'd VWR as just re-badging products and adding a fat profit margin but that hasn't been my experience of them.
I presume that spring ratings are defined by a range rather than a fixed weight value or force.
