As far as the Suplex kit is concerned, I can only put it down to the fact that the springs are much longer, so come closer to the exhaust. It must happen on the standard suspension as well as the Empire modded ones. Has anyone with a standard car upgraded to Suplex yet and can confirm that?
Paul - I fitted the SPAX adjustables to my car without Empire (still is I'm afraid - life is too busy...) and had exactly the same problem. The springs on the SPAX adjustables are also longer and therefore when I adjusted ride height to get horizontal track arms, both headers were in solid contact with the shocks. So I simply wound the ride height back to where it started (when the car was on the OEM SPAX units) and all seems OK. I suspect that there are variations in each build that means the shock-to-header gap varies all the time. Spoke to Technical at the Factory and they broadly said as much.
Partial fix is to release the two nuts on the header-to-cylinder-head mount and 'ease' it up a little. Then retighten and it certainly helps. Empire fitting very very soon I hope!
