Hey. I'm looking to make my car lighter. period. So far I've gotten a carbon fiber hood, im setting up to get lightweight corboreu seats or sparco, carbon fiber doors, a carbon fiber trunk, an aluminum radiator, and rear-seat-delete, (maybe lightweight wheels-deciding on overall look).
Anybody know how much those mods would take off my drag time on a stock GT? My setup is, I'm trying to lighten my car, then put a great cooling system, exhaust, then CAI. Ideas? Comments?

 

5zigen rims look great and are light, coil overs, driveshaft/flywheel, panhard bar, k member, spare tire, lightweight battery

 

get a light wieght drive shaft for sure. You loose a good amount of wieght and gain some rwhp.

 

If you're referring to what you'd run in the 1/4 with all the weight reduction... I imagine you'll drop 2-3 tenths.

 

A couple of comments:

First off, the OEM radiator is already aluminum. Aftermarket ones are usually larger, which means they are also heavier (and they hold more coolant, which makes them heavier still). I wouldn't buy an aftermarket radiator unless you have having overheating problems....and that won't happen unless you are running forced induction (blower or turbo) and are making a lot more HP than stock. It's not needed on a mildly modded car (CAI, UDP, headers, stuff like that) If you aren't overheating with the stock radiator, then a larger one is just going to be more $$$ spent for more weight.

Read this past thread about weight savings, it has some very good suggestions.

To summarize, your best bang-for-the-buck weight savings is going to be the "free" type of mods detailed in that thread.

Then, hit rotating weight: driveshaft, flywheel, pressure plate, wheels & tires. Removing a pound of rotating weight is like removing 4 lbs of stationary weight.

Finally, I'd look to stuff on the interior. Things like race seats, front swaybar delete, and upgraded suspension parts (K-member, A-Arms, etc.) are usually a lot better bang for the buck than carbon fiber parts are.
