I think the front suspension setup on the newer cars is much better than previously, so that the improvements offered by the Suplex refinement kit are not so obvious.
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.
Is it worth the asking price? Only the customer can make that judgment. I was happy to spend the money, but only had to pay for the kit.
