Basically full exhaust and 200 pound diet but FULL interior.
PPE headers (no cats 1 pound or two lighter)
Borla catback (no cats and 10 pounds lighter)
VOLK RE30s (40 pounds lighter)
Lithium battery pack (40 pounds lighter)
2 piece RB Racing rotors (20 pounds lighter)
No spare and jack and tools (50 pounds lighter)
BR racing coilovers with Swift springs(10 pounds lighter)
Planned mod: clutch type LSD and front buckets. I'll probably be a 3400 pound 11.8@122 car and since there are no other power adders besides NOS, it'll just be a very reliable road racing car/DD for me for a few more years.
I know this is a BMW site so I don't usually talk about my cars, but thanks for asking and glad to share the info.
You could probably just google me and I'll pop up. You can look me up on dragtimes too for the slips.
