147 2.0 track / racer help
Need some advice from anyone who knows about preparing a car for events.
I have had my 2003 2.0 147 since 2005 and following smashed sump last year I spent £3k+ on a refresh- new engine, suspension, gearbox (and obv. timing belts clutch etc) and as I know Ill never get that back in a sale I have decided to turn it into a track car or race car.
So far I have 35mm H+R lowering springs, new sport shocks, all interior gone except dash, sports exhaust with 3 cats in place (but no after cat lambda), DIY ram air with high flow filter.
Next up is an OMP roll cage, plumbed fire extinguisher, racing approved seats, removal of AC and heater, plexiglass side windows, removal of spare wheel well, underbody aero/Seat Leon Cupra front lip, and slick tyres.
But I havent decided whether I will stick purely to track days or if Ill enter a few races locally. I dont wanna make changes that will bar me from entering races.
Anyone any advice on whether cams and ITBs are allowed?
will removal of cats and lambdas altogether cause power increase or loss?
I haven't touched the airbags, should I take them out? I'm assuming they wont work without front seats anyway.
Can I use thin plastic for door cards or will this be fire hazard?
I have 215/45/17 supersport alloys, should I change them to get better performance?
Poly bushes, they seem crazy expensive for all they are, are they worth it? (my suspension has only covered 1k since being completely replaced.)
