road race questions
here you go "jonduke" for a better post for weight reduction
not that i would do it , but the seach button works great
Carbon fiber hood and trunk: -14kg
Light wheels, depending on wheels: -10 kg
Air conditioning: 20 kg
AYC: maybe 30 -40kg
Light flywheel: -1kg but it will feel like you took of 100kg in 1st gear, 60 in 2nd, 40 in 3rd etc.
remove:
Small battery/sparetire/carpet/backseats/new steering wheel "no airbag"
Empty I/C sprayer and windshield wiper fluid.
remove the stereo, remove AC, replace front strut bars with titanium one, carbon fiber front and rear trunks, fiberglass front bumper, remove rear door panels...
strip your trunk... 41 lbs (spare and tools), 6lbs (carpet), 3 lbs (lining and sound deadning). Emptied washer fluid tank - 3 gallons /10lbs maybe, Front bumper beam-13lbs, rear bumper beam -17lbs, - Floor mats 4lbs
94 lbs ttl
front and rear bumper support...saves 35lbs...'
All the AC stuff weights 60+ lbs. You can always remove all the smog stuff, like the charcoal canister, EGR, and all the associated vacuum lines if smog is not a concern to you. Change all windows from glass to lexan. Build fiberglass or carbon fiber doors. Carbon fiber all your suspension arms, driveshaft, axles. After you've spent all this money, you might as well go buy a porsche 911 turbo.
the only other thing that other people haven't mentioned is carbon fiber fenders, and there are weight savings from replacing the hood, i don' t know why people say it's pointless the apexi evo saves almost 8 pounds and with a varis hood you can save almost 6. and don't run low on fuel if you're gonna take any turns, the fuel tank is shaped like a saddle and you'll get really bad fuel starve and destroy something.
replace not remove:
battery, fenders, bumper(s), hood, trunklid, wing, wheels, tires, brakes, coilovers, front strut tower bar, radiator, intercooler piping, exhaust, racing seats, drive shaft, flywheel, pullies (not recommended), and all interior paneling can be replaced with cf pieces from tado. and i think i didn't forget anything.
biggest bangs will be seats, if you actually spend 2gs a seat you can shave 20 pounds per seat. exhaust is at least 20 pounds more if you get ti (keep in mind there are a lot of fake ti systems out there, jic and greddy make the only real ones i know of that aren't japan only). trunk lid will save you almost 15 pounds if you get the best (all american motorsports) but about 10 if you get a varis. replacing the front bumper with a gialla piece will force you to remove a bumper beam so net you about 15 pounds. wheels can save you about 5 pounds a wheel, ce28 in 17x9 is 14.6 pounds a wheel. don't spend money on light wheels and get heavy tires, get some nice rubber (basically don't get heavy falkens). you already did battery and that's a huge one up to 20 pounds. all the other mods are tiny weight savings that will add up, maybe with all the other stuff done that i listed you can shave another 20 pounds. and remember i didn't list anything to remove cept the bumper frame, so there's much more there.

thanks for all the feedback
the rules for the class im running in the scca is
full roll cage
strip the trunk compartment
full interior
stock driver seat has to go.... one piece race seat
stock size wheels but can be aftermarket
stock springs
can change the shocks
air cleaner element
can flash ecu....or do anything i want to it as long as it stays in stock box and the check engine light doesnt come on
and i can take out the ac and the radio
i can update and backdate the evo...that is why im going to trade headlights for weight and get the rs trunk lid
i picked the mr over the rs for the 6 speed and the abs brakes

thats pretty sick good luck in your class,i agree the rs is tight but ABS is definently your friend,i dont know what your budget is but theres the MOTEC 800 that would fit in your stock ECU cartridge and is a full stand-alone management system,can you remove A/C?

Man, too bad you didn't see my add before you bought the MR. The MR is a nice car, almost too nice to tear up into a race car.
