Just curious what you guys thought was possible, I am considering doing this in the near future. If you are asking yourself why, I don't use my car for a daily driver, and I think it would be fun/different to have a track car that was 2500 lbs (if possible) and 500 WHP on C16. Oh this would be a full out gut, no air bags, sound dampening, ac, etc, with a cage.

 

carbon fiber doors.
no dash
magnesium wheels
titanium bolts
only one race seat
no carpet
new steering wheel and no passenger air bag
aluminum coil overs
titanium lugs/nuts
titanium exhaust, cat delete pipe, downpipe if you can get one
no front or rear crash bars
lexan windows

it's all about how much you wanna spend

 

You could remove all of the paint from the exterior of the car. That should make for about 20 lbs...

 

remove the engine too. That's ~175kg (386lbs)

 

Ok u went to far on that one...

 

That's cute fella's if you don't have anything worth reading than don't bother. I was actually serious about it. I am looking at more on the removal side of things not replacing, what kind of weight reduction I could see removing things such as air bags, window motors, ac, etc....

 

There is not 500lbs worth of removable items from the car... more like 300 if you're not replacing parts

 

What kind of things would be replaceable and resonable price wise?

 

everything that is replaceable and is significant in weight reduction is going to cost some money. But if you're trying to buid a purpose built race car, then you're going to sink some money into it.

CF doors -- I would guess around $1000
Pulling all seats and just having a race seat -- About $400
Magnesium wheels -- $2500-3000 (but it's unsprung weight)
lexan windows -- no idea. rough estimate around 1000-1500

The front and rear crash bars are 30lbs
mini battery saves about 20lbs
titanium exhaust saves about 45lbs
air bags would be about 30-40lbs combined
A/C would be about 30-40lbs
carpet in the whole car - about 60lbs
pulling stock seats -- about 20lb for passenger seat and 10lbs for rear set
rear window sprayer resovoir - if full about 10lbs
IC sprayer - about 10lbs if full
front window sprayer -- about 10lbs
Dash -- maybe 15lbs

You're sitting around 300lbs now. And that's all I can think of.
You will need to replace parts to get to 2500lbs

 

What is the difference in a hood, trunk lid, and maybe an MR roof (i have a sunroof now)?

 

this is an all out approach, and it is a very good one, but u can get rid of speakers, wires, seatbelts, no stock gauges, etc.

btw this my 500th post

 

I think that it is a great idea and I have been contemplating the same thing. I would guess that even by just reducing the weight of the vehicle by 300lbs you would be astounded at the performance difference. My S2k weighs what, about 2800lbs so that is about 400lbs less than the Evo and that car makes the Evo feel like a muscle car. It is amazing how much more agile and quick it feels.

 

Other items are lighter brakes, tires, rims, heater (all ducting althought that would go with the dash as well), light weight drive shaft, bumpers front and rear, sound deadining material, fuel cell, and chromoly roll cage. Titanium, carbon fiber, and aluminimum parts everywhere you can replace them.

 

Yeah I like your thinking, I am going to start by taking everything I can (meaning what I don't need) out of the car and than go from there with replacing. I really think you could shave 400 lbs with just the removal of unecessary stuff. than after that go for replacing. I just get the chills thinking about his car at the drag strip and road course that much lighter and with 500 WHP

 

basicly you should try to shave weight off the front of the car if you can....

CF hood,
CF fenders,
Fake plastic headlights,
aluminum roof
