Suspension, Good Price?

[Benderloch]

Hi All

I am in the process of discovering what condition my new cars suspension is in,and from what I can tell it’s all original apart from new rear M spring ( black with blue dots) therefore about 15mm lower.
I found this on the German eBay

https://www.ebay.de/itm/4x-BILSTEIN-B4-STOsDAMPFER-VORNE-HINTEN-BMW-Z4-E85-Z4-COUPE-E86/232434075819?fits=Platform%3AE85&hash=item361e2688ab:g:xdQAAOSwhWFaUzMp

Seems good value ( maybe only till 31st Dec )
Any suggestions on front springs to match? and does this look like a reasonable way to go. Car has 85000 miles on the clock.

Thanks

Looks reasonable - I just ordered a full set of B4 dampers as well for my coupe from Balance Motorsport. Came in at pretty much an identical price as that eBay advert once shipping and the eur-gbp conversion is made, but a UK supplier.

Can't vouch for their service as I've only just ordered from them for the first time, but all looked OK!

As for springs I've gone for Suplex to maintain the M-sport height off eBay. Fronts Suplex 06248, rears Suplex 06231.
