Doesn't weigh hardly anything. For me it traps heat.

Just cosmetic.

As far as the exhaust...I am actually worried about loosing too Much weight in the rear. Remember my goal is balance. I know many will say that can be tuned out but also take into consideration that I have not spent the money on adjustable suspension yet and this car will be tracked.

I can not justify a super light weight exhaust (from the CAT's back). So from the CAT's back I am aiming for power not weight. Header and CAT's are a different story though...that will be as lite as possible.

I wouldn't get too worried about the balance. I mean, I try to keep balance in mind, but I've definitely dropped a lot more weight from the rear than the front in the net, seeing as I've probably added front weight with things like my add-on coolers, the G3 intakes, the oilpan, the z-speed tray, etc. Whereas the rear of my car is completely stripped to the metal at this point in the interior, there's nothing aft of the seats but the airbag controller box, minimal wiring (I removed all unnecc harness wiring), and my relocated battery.

Car still handles fine with a mostly-full tank of gas (required on track until a fuel starve fix is commercially available), and my rear swaybar is still set to full stiff (if the rear got so light as to make the rear too skippy, I could soften the rear sway setting to offset a bit). I'll be more worried about balance once I can run lower on gas w/ phunk's upcoming fuel surge fixup.

^ more reason to run wider tires up front to handle load. Wouldn't you say?

This is true no matter how you slice it.

What's your current setup if you don't mind me asking?

Edit: Never mind...clicked sig...lol

Just coilovers to corner balance. Adjustable suspension for alignment.

figuerd you'd have those if your in this thread!

cavemancan · 07-16-2012, 11:00 PM

I meantioned before I didn't...Mostly due to the fact that I've only had the car for a few months now. Eventually it will be a possibility but not yet. So my intention is to optimize what I have.

cavemancan · 08-06-2012, 10:53 AM

Question: I read somewhere that someone modified their hood to make it lighter. Anyone have a DIY or more information/pics they could share I am really interested in this?

BTW...

I decided to go with Fast Intensions after hearing the FI cat back plus LTH combo...simply put...HAAAAMAZING!

Question2: I'm researching wheels. For obvious reasons Forgestar F14's are popular but I am not sure I like them (although I recently saw a set with the dark bronze finish that actually looked good). Do you all know of any wheel under $3k that comes close to 23 lbs and is a 19x11?

KingJoseph · 08-06-2012, 02:33 PM

The Berk Cats are 5.5 lbs a piece for 11 lbs total, versus 21 lbs for stock.

Shamu · 08-13-2012, 09:28 PM

Anyone gut stock hood yet? I'm thinking that's best approach. I'm selling boat anchor Siebon TS hood cheep!

How about gutting rear hatch too and then installing plexiglas ? Weight savings?
