Well, I thought that I'd better see what stuff weighs before it goes on the car, so here we are...
OEM wheels with tyres weigh 20.0kg - lighter than I thought.
Team Dynamic Pro Race 1.2 alloys and tyres weigh in at 17.6kg - a saving of 2.4kg a corner.
Spare came out of the boot = another 14kg gone.
Bilstein B16 PSS10's weigh 20.5kg including the box!
Milltek Stainless steel Turbo-back exhaust system weighs 19.4kg including the box I laid it on.
Lightweight race battery weighs 7.3kg
Once the OEM suspension and Exhaust is off I'll get a weight saving and post it up.
