My dealer believes that one can use 500E springs/ shocks in a 400E.
Any thoughts about the accuracy of this ???
Also, would this increase the performance of the 400E more than that obtained by simply using H&R springs with Bilstein Sport shocks ?
If so, would this solution be cost-effective, namley if the 500E parts cost orders of magnitude more than aftermarkets, while providing marginal performance improvement, then one might reason that the solution is not cost-effective :-)
thanks
