Weight reduction

OK, I know we have a 3600+ lb car so small weight savings take a while to add up. However, the relatively minor changes I've made (especially for track days) seem to have made an arguably significant dent.

Enkei PF01 wheels/Hoosier R6 295/315:
Front 60 street vs 45 - 15 lbs each x 2 = -30 lbs
Rear 58 street vs 49.2 - 9 lbs each x 2 = -18 lbs
Corsa Extreme axle backs (pair) 54 lbs stock vs 24 lbs = -30 lbs
Kooks Off-Road H-pipe 32 lbs stock vs 17 lbs = -15 lbs
Side pipe delete 5.5 lbs each = -11 lbs
Kooks LT headers vs stock manifolds = + 3lbs
Roll bar, mounts & harness bar +69 lbs.
Rear seat delete kit +12 lbs.
Remove rear seats and belts and factory mounts -54 lbs
Swap to the Tiger Hood -17 lbs
Remove washer bottle incl fluid -8 lbs
Remove flat repair kit -5 lbs
Sparco race seat 35lbs versus stock seat 46lbs = -11 lbs
302S tow hooks +2 lbs
FRPP air-to-oil cooler +8 lbs
1-pc DSS aluminum driveshaft vs stock -21 lbs
DS saftey loop +10 lbs
Trunk liner -7 lbs
Passenger seat -46 lbs (track only)
Watts link versus panhard bar +15 lbs
Rear axle weights -5 lbs
Battery relocation kit +25 lbs
Remove A/C condenser, compressor, lines and belt -21 lbs.

Total weight savings so far is 116 lbs with passenger seat and 162 without it.

With a curb weight of 3630, I'm at 3514 to 3468 with or without the passenger seat.

removing fuel tank evaporative system under spare tire well is worth 20lbs.
I am told that this will not create code errors if the vents are re-connected instead of running through the evap unit but have not tried it yet myself.
(good place to remove weight)

Has anyone removed this yet? Thinking about doing it next weekend. If the CEL is an issue can it be taken care of with a mail order tune from BAMA?
any tuner can turn of the rear 02 sensors.

I emailed American Muscle and they said they dont know if they can remove the CEL. Supposedly no one has taken off the evap as far as they know. ???

Something to think about with SLAs:

You break something in that front end, your weekend is over. You can't just run over to the nearest dealer and pick up a spare part. I've seen more than a few racers taken out of contention because of custom part failures.

Agreed. I was tossing it out there more just to get Pete going. :)

How much lighter is it ??

Dont buy that junk. There is alot more into it then just taking some square metal and welding it together. Ask them how they stress tested it? What material it is made from? Is it semed square tubing? If steel what did they do to keep it from rusting on the inside? There are alot of companies whom build these things and even reputable companies that build them for today and expect you to know it will not last or hold up over time. How did they test it?

They test it by winning Grand Am championships with it....

Yep. It will no doubt make you faster on the track. I've run with some guys that have them installed and they make the car unbelievably nimble. It's just at the extreme end for those trying to get every last bit out of their lap times....and willing to invest in it.

So does the KB unit require you get their LCAs too?

I don't think so. Most are designed to couple with stock locations and mounting diameters, etc. The exceptions are kits that change the stock geometry like SLAs (Griggs and Agent 47) which end up using totally different parts.

KB hasn't been involved in Grand-Am with the S197, but they did win the SCCA World Challenge with it.

Also to whoever posted the BMR stuff, do yourself a favor and leave their drag-race oriented parts on the shelves. They don't understand what it takes to design proper road-racing parts.
