Well I think they're strange.

Yea, I mean how can you not appreciate the engineering of this machine, its awesome!

That is an interesting insight to me. I have always kept those with my daily drivers. I wonder though if I can perhaps delete a speaker or two, depending on weight...of course.

If no one has weighed their sound system and posted the results by the time I get home (~December) then I'll be happy to do it.

Attached a photo of the HKS 4-2-1 Cat-less headers.

Weight is 6.2kg / 13.65lbs

Note: Weight includes both O2 sensors, and may result in most likely a 0.1-0.2kg drop.

EDIT: Image didn't attach, now there.

Suspension & Bracing

go to their site, derp.

Any info on suspension parts?

What specific Suspension parts are you looking for???


Bill

Has anyone weighed the OEM front bumper beam vs the Beatrush beam?

Will be interested in knowing if changing to coilovers will save any weight:iono:

yes it does.. Depending on the coilovers .. I saved about 2lbs a corner with KW Var3 and camber plates

Bill

I'll be weighing my OEM suspension parts next month. I'm not going to take my coilovers off just to weigh them, but I'll definitely weigh them if I ever have them off.

I'll also weigh the bumper beams. If you want to compare it to Beatrush, you'll have to get the weight of the Beatrush beams elsewhere.
