Ahhh that actually makes sense! Thank you! Looks like I'm off to have this done again then.

Show off! Whats that all mean then?

Ello! I'm running a 1.8L 1994 MX5 MK1. It's lowered, the gap from arch lip, top centre to wheel centre is 320mm. It's running Rota Slipstreams 15" x 8J ET20 Shod in Khumo KH31 195/50/R15 V tyres. Since going onto these wheels and tyres (from the standard 14" wheels) I've picked up some pretty awful tramlining. I also think the car understeers a bit too much. I had the car aligned (on a Hunter rig) When it was running on the 14" and I've had it realigned now that I am on the 15"s. I asked the tech to address the understeering and if possible the tramlining. This is my most recent berfore/after printout : A trusted friend has looked at this printout and doesn't feel it's correct in terms of correcting understeer or removing tramlining. I've also posted it on an MX5 forum and one of the guys who is involved with mx5 race prep has said : "I do not profess to be an expert but I would say that you are almost guaranteed to get understeer with those settings and tram-lining. You are on strong offset and wide wheels so more toe in would be required and to kill the understeer you either want more camber on the front, up to 1.8 deg total (what ever that is in minutes)or reduce the back to 1.2. I would go for increased front with as much caster as they can get." I really have very little idea what does what in the geometry of suspension. I'm an electronics man myself. I'd be interested in the thoughts of others please!
