Been working on a front weight reduction project the past few days. Unfortunately not a lot of weight lost for a lot of work done.
Took off all the Non structural metal upfront (Headlight bucket, Radiator T, Fender brackets). Had previously swiss cheesed the Radatiator T but for some reason I didn't record the weight, but I did clean up the holes and added some more Bought this to do some clean holes. Still needed to drill out 1/2" to use it All the pieces weighted come to 11.5 lbs After a lot of drilling and hole punching was only able to save 1lb But this mission wasn't a complete waste I was able to save some weight removing some unnecessary brackets. One on each side brackets holds up some thing for the headlights (mini Balast??), easily screwed in without the brackets. Bracket for outside temp sensor I believe removed, plugs right into radiator spot went from 2 horns down to one, and removed windshield washer hose. Brackets,Horn,Hose =Got a 1.25lbs loss! Also saved a 1lb from replacing bolts with titanium ones and some unused from the brackets In conclusion easier to find things to remove, or get lighter pieces than drilling holes which hasn't given me good results. Not sure how the Opera S2000 got 700lbs out from doing it! Total Savings: Speed Holes = -1lb Useless Brackets= -1.25lbs Titanium Bolts= -1lb NEW WEIGHT 2337.25 LBS |

Seeing as my airbags are removed, I could remove these then |

I did order the Injen Evolution intake (taking a while to ship but I got it at a much lower price). Im not expecting 15hp like advertised but I think its the closest to the Gruppe-m style with a straight shot to throttle body for a fraction of the cost. Main difference is it only pulls in air from one side instead of 2 like the Gruppe-m. So the stock style setup will be gone soon https://injen.com/i-30497562-injen-e...m-evo2000.html |

Could be, I have mine off and didn't notice a loss in power. Maybe my high flow air filter evened it out |

Plus there was some extra wiring upfront there for fog lights as well. Should be good for a few pounds of copper out |

Lighter Rear Brake Kit
Finally got around to this, my Lightweight Rear Brake kit
So what is involved in this kit: -Rear Subaru 2-pot conversion (Refurb Calipers from Rock Auto), Torque Solutions adapter -Metal Bar from home depot for pad spacers -Single Vane Rotors from "base" gt86 overseas. $35 on ebay I recall an old post with Robispec claiming 3lb lighter per side with the Subaru 2pot. Counting in the adapter I only got 1lb lighter per side fully loaded. a little over 5.5 lbs for the 2pots + adapter + spacers added .25 lbs. Only showing 4 here I ended up using 6 Stock loaded Caliper 6.75 lbs Single Vane Rotor 11.25lbs Stock Rotor 13.25lbs Had to do a little grinding to get it on better but really on a small 1mm casting was removed Adapters Bolted on I used this stuff sandwiched between each backing pad to keep them from vibrating against each other So I used 3 plates on the front side, no plates on the back side. Although I will probably make a 1/16" thin plate for the back side so far it hasn't been necessary Looking Good ! Haven't done any crazy 100-0 stops but bedding in and driving around no issues or noises so far. Stops like it normally did If this has issues I can just put the stock rear rotor in and keep my 2pot setup So what was the point of this? To get lighter of course! So you lose 2lbs in the rear from the 2pots, and 4lbs of rotation mass from the rotors 6lbs Total! New vehicle weight 2331.25 LBS |

Thanks for all of the details.
I think ScoobySouth did a similar setup with the KNS adapters a few years ago. Are the shims required? I know these 2 pot brakes were from the old WRX, and one model of the WRX had the solid rotors. I wasn't sure if the 2 pots would be fine without the shims. Sent from my SM-G930P using Tapatalk |

If you use the stock frs/brz rear rotors then it should be a direct swap without any shims. The single vane rotor im using is much thinner about 10mm thinner, don't know if the brake pistons have that much travel to not use shims The best setup would be these calipers with stock size 2pc rotors. People say these exist but Ive yet to see them Last edited by SuperTom; 02-09-2020 at 07:35 PM. |
