I'm cheating a little due to having an RS, but I am at 2850 with full interior, minus rear speakers and belts. A/c delete helped a lot along with aluminum exhaust and IC piping. I've done most of the bolt on weight reductions, but haven't ventured into cutting anything up yet.

Kaj I'm after a similar goal of 2700lbsin street class trim in an MR SE so I'll let you know how it goes. I've also done the ACD relocation and will be redoing it on the new car so I'll detail it. Pretty straightforward just lots of work.
As as far as the intercooler, I guess I'll let everyone in on my secret. Blitz SE. Tube and fin, super light. Butt dyno tells me HP was gained, my only confirmation was my injector duty cycle jumped like 8%. Nice bonus since I only got it to help with heat soak (I live in Florida) which it definitely did. It's also dirt cheap for what it is. Like $600 shipped.
BTW does anyone know if the Robi Spec hood and trunk are still available? I'm dying to drop nose weight and the stock hood is hard to beat.

Far as robi anything those were all through fiber images if they're still around.
So do one of ya'll have the weight diff's of the Blitz vs X?

AFAIK Robi is out of business as I've seen a few posts recently where he hasnt gotten back to people. Its a shame as I'd love a hood and trunk...
What kind of info do you want on the relocation? I did mine this past spring and took a good amount of pics. I said I was going to do a writeup but have not got around to it. The concept is simple but if you have any specific questions or want some photos ask away and Ill see what I can do to assist

Also, one thing I forgot to mention and Im sure most of you in here have already addressed this is seats. I'd love a fixed back seat with more side bolstering and imagine there is prob some decent weight to be dropped with those as well. Ill have to do some research but off the top of my head I recall the stock recaros with rails in the 40# range so racing seats around 20# doesnt seem unreasonable adds additional support and I could offset the cost by selling the stock seats.
And on a different note what exhaust systems are you guys running? I'd like to replace my catback with something that is lighter if possible but my concern is that most of the lightweight systems are very loud and given that my car is already pretty loud Im not sure I want that. Can I have my cake and eat it too or does something have to give?

I have a corbeau fx1 seat (I think that's what I have). Not FIA certified because autox... With the harness and side mount brackets to fixed base it weights like 1-2lbs lighter than stock. My harness is really heavy and pretty annoying so going back to stock seatbelt with just the benefit of bolster to improve over stock.
Moving to a fixed bottom mounting bracket would most certainly save a few more pounds but I don't see getting down to the sub 30lb range after all is said and done.

WTF I thought a bunch of racing seats were like 20#!? I take it the brackets add weight pretty quickly?
I have the BR quick release harness bar and Schrothe harnesses, forget the specific model and yeah it adds some weight no doubt but its far better than using just the CG lock so its a sacrifice Im willing to make.

Got a link to that slider/bracket? I'll have to pull the seat bracket off and see what just the seat weighs but I think its around 20 lbs. I was also adding the harness in my weight since it was additional and that may have been another 5lbs of stuff. Will certainly revisit that.

I believe the seat itself was around 13lb.
