Hi all! I just found this forum and I feel confident that this is the place to share my build So, I will be grateful for any tips and tricks you have for race build Z3. The idea currently is to be street/track car for 2019 and if does good this year... will be full race mode 2020. So, up to now: BODY: - BMW Z3 1996 - Fiberglass front hood - Fiberglass fron bumper - OEM Widebody rear fenders Current weight : 1158kg without driver Engine: - BMW M52B28TU stock engine - BMW M54B30 intake camshaft - Sport exhaust headers - Full custom exhaust with 2x55mm pipes - Software delete of second lambda sensors - software deletion of EWS - software tuned the redline limiter - software tuned with better vanos control - software tuned for better DISA control Drivetrain: - Getrag 220 with added racing oil additives - LSD with 3.91 ratio, custom built with racing specs and racing oil, 3 friction discs and with better acceleration ramp - 1.5Way - Uprated front brakes with 300mm discs - stock rear brakes due to lower weight compared to stock - Full upgraded front suspension using BMW e46 wishbones, hubs for wide track - full adjustable low budget coilover system - 20mm spacers on all wheels - wheel specs: 8,5J / 10J 17" with 245/40/17 tyres - also set of style 66 8J / 9J with 235/40/17 Interior: - two racing low budget seats - two racing safety belts - racing steering wheel - full stock interior Some pictures from last summer: Here I started test fitting the widebody fenders: Here I received the fiberglass hood and front bumper : The big LSD and E30 big axles: And some more progress: And after I painted it (alone in front of the garage... dont look up closely ) I had one time attack event already. I am VERY pleased how the car drives and goes on the track... but of course .. I am looking for upgrades already So I borrowed one wheel from a friend to test The wheel is 18" 10.5J ЕТ25 with 270mm slick tyre. I am with 20mm spacer so effective ET is 5 BACK: And Front: So.. I have sold already my 17" and I am looking for wide 18" rims ..
