Weight savings....what else?

Hey Nick...thanks for the ideas. My feedback below...

1. Based on what others have posted thus far, it seems like the Michelin Energy Savers are where the biggest gains are to be had....so I think I'll be going with those. As far 13" wheels go, the Volks don't come in a 13" with the lug pattern needed for the Prius. Is there another manufacturer that makes a lighter wheel than the 15" TE37 (8.86lbs)? Non-CF? Also, I assume the aero covers are flush hub cabs to reduce turbulence? Where can these be found/purchased?
2. I intend to remove anything that isn't necessary for practical safety and emergency repair. Still undecided as to whether or not to remove the jack and spare.
3. The lightest exhaust for the Prius that I know of is the Tanabe Concept G...but it is stainless...not Ti. Who makes a Ti exhaust?! Or are you implying a custom fab?
4. Again, who manufacturers drilled out/Ti rotors? Any idea?
5. I will test drive before and after but most likely will end up doing this.
6. Again, who makes lightweight/Ti radiator for the Prius?
7. Easy.
8. Maybe...I will have to look at the implied risk of heat exposure to nearby components.
9. This is a possibility...but I am also waiting for pics of the VS2 from Seibon...it's supposed to be a CF hood with the vent already cut out.
10. Will explore insulation removal. I talked to Tanabe and they 'think' their shocks/struts are lighter based on logic that they are smaller in diameter than stock, but they could not confirm so I will have to test myself when I get them.

Thanks again, Nick. If you can answer any of the above, it will be a great help.

 

OK...so I did some research on a few of the above. Bulletproof Automotive looked into Ti exhaust. JDM does not make one. They thought that Tommy Kaira did, but there's is stainless...not Ti. However, a company called Top Secret tuning out of Japan (I am not affiliated nor I am endorsing them) DOES make a Ti exhaust, and Bulletproof is checking availability for me. He said price would be around $1,360 for the system...which isn't so bad when you compare it to stainless still alternatives at $1,000+. He also did not know whether the kit included CAT or not...and will let me know on that as well. Do you really think there is that much to be saved in the exhaust though? Can't imagine it being that terribly heavy to begin with...but I could be wrong.

Also, I could Race Shopper for the brakes...there are no Cross drilled rotor kits available for the Gen III's yet. Guess it's a waiting game until mmod manufacturers start making goodies for these cars.

More to follow...
