But owners of older cars, where the rebound spring is in compression at static ride height, will experience a much greater improvement in the compliance of the front end. For me, I was particularly impressed by the performance on rough potholed roads, of which we have a fair amount in Gloucestershire. On smooth tarmac the improvement is not nearly so noticeable.
I think that Hamwich makes the key point!
Any car where the rebound spring is loaded at static ride height, when loaded with 2 people, will be vastly improved by the Suplex kit.
On a 2009 Roadster, with its 205 profile tyres, it made a very significant difference, particularly to low speed steering load when parking.
I had it fitted by Williams, along with brake reaction bars and AVO Rear shocks. All in all it made the ride acceptable and considered it good value.
