Revalve of Bilstein Shocks?

"Eibach lowering springs (25mm lower)"
If you are talking about Eibach Prokits, although they advertise one inch drop, you probably won't get anything like that.
So if you have the stock Bilstein sealed strut/shocks they should be fine if there is no sign of oil around the tops.
 
On my car I found that Prokits ride only about 5mm lower than stock 92+ springs,
 
Manufacturers advertised drop can be a bit dodgy because they often seem to compare their product to brand new '90 model springs that are about 3/4" lower  higher than 92+ springs anyway.
Also your old 20 YO springs have sagged as well.
 

Thanks for the replies. I thought the 92 cars were lower not higher than the earlier 90 cars? Mine runs particularly high and I assume they are stock but maybe not, the car was used as a tarmac rally car. Josh did you notice much of a drop with the Eibachs? I reckon you would need to go custom for the linear springs.
 
Are you going to Wakefield in January?

No probs mate - the springs were already in there when i bought the car so I couldn't tell you about the drop sorry.
However, I don't know whether they sagged or what, but they were on average 5-10mm too low for REGENCY specifications here in SA. So I had to get them re-set/lengthened.
 
Wont be able to make it in Jan unfortunately, just started a new job (no leave).
