Okay guys, I have an Evo nine MR. what kind of weight are you guys seeing after doing reductions?
I am pretty much okay with removing or bolting on parts. I am not looking to cut and replace any body panels.
I am on the fence as far as ditching the Evo and going with a tube framed kit car. Though it would be a million times easier to work on the 818, I would really like to keep the Evo since I will be paying off this month.
The 818 will be 1900 pounds with 300whp, while the Evo is at 450whp on a race tune.
I don't expect the same power to weight ratio, but can I get close?

my SM evo9 was around 2990 with nothing crazy done.

still had carpet, full dash, full glass, no carbon, steel exhaust, full door cards.

i would think if you are OK with extensive cutting (dash bar, carpet, insulation, etc) you could get to 2700-2750.

If you wanted to buy some lightweight parts (subframes, mustache bar) you'd be mid 2600.

There are extensive threads on this if you wants to spend hours reading though them

2990. Nice! My first goal is sub 3000. I have no carpet or rear door cards, but have the rest of the stuff you mention. I know my 6spd and roll bar add a bit of weight.. but I wonder what I am missing, as I'm not close to 2990.
I am thinking to ditch the dash bar and insulation behind the dash. I also plan to get rid the crash beams, since I don't really drive the car on the street.
If I could reach 2800lbs that would be awesome. 2700 is my goal. 26xx would be lighter than my old Integra and even more awesomer LOL
I'd love to do brake rotors, driveline, front sub frame, etc... but damn. That's a lot of money. Maybe later, but I'd like to do all the "free" stuff first.

Thanks for your input. You give me hope :lo:

I would leave the crash bars, or make lighter weight versions. Could save you a lot of money in a minor impact.

My car was 2925lb (with stock pass seat, no carbon, 1pc rotors, etc) in SM trim at 2014 nats. My goal is 2820. 27xx will be hard without $$$ or cutting stuff up.

Mines about 3k even with cage. I think it was right around 2750 before then. This is with 0 interior and gutted doors although I still have the dash bar, rear sound deadening, etc. I only took out the things necessary for the cage install. However, in doing to, you will start to tilt the weight bias inevitably more towards the front because a LOT of the unnecessary bits are all rear of the engine bay. So keep that in mind.

I figure If i crash on the freeway to/from the track or while there, they won't help much LOL.
A friend of mine was rear-ended at a stop light. The result was a salvage by the insurance company.
So, either way, really.

how in heck are you guys doing it?? I have an aluminum roof, etc. I'm not even close.

There was a discussion about that a while back. Consensus was that it's bad enough as it is and the shift wouldn't be enough to really matter. Or, at the very least, be worth it.

You could have all kinds of low speed impacts. A slight lap from behind, or giving someone a light tap. The car just barely doesn't stop in the sand box and kisses the krail or tirewall. Having a crash beam could same expensive parts in those scenarios. Just because you're on a track doesn't mean it always going to be a high speed full on crash.

If you get into an accident and insurance finds out you didn't have the crash bars you are SOL.

Anything is possible.

Ditching the A/C plus all smog gear should dump some weight.

kaj

Can't lose the smog stuff (I'm in CA), but I may be ditching the A/C. I have to leave the rest of the HVAC, though. A/C pump/bracket/condenser looks to save me 25lbs or so.

Biggiesacks

You can also lose the pusher fan for the condenser.

kaj

iTrader: (60)

oh, yeah. And then I could plumb a better oil cooler to where the condenser was.

Biggiesacks

Damn thats a great idea, i had never even thought of that.
