E30/Z3/Ti can use Double adjustable Koni's that are meant for SN95 Mustangs. That is what TC Kline was using and TMS was using Bilsteins from a Ford E350 van for the J stock initially they have their own serial number for them now.
Be surprised what you can and can not use. Believe some of the R3V guys were using Pontiac Firebird stuff for a bit too. |
