Great update. How is the road noise?

With the rear quarter panels gone I can hear the wind whistle but that also might be from having everything removed from the trunk including the sound deadening material. I took out the rear seatbelt assemblies while I was at it since there's no longer any seats and very briefly started chipping away at the black (presumably) sound deadening.Great update.

Not sure if you've seen by now but the enkei rpf1 is lightweight and should be less then $350 per wheel. I went with excessively wide 18x9.5 at ~$350 per wheel and they're listed as 17.4lb directly from enkei. Thinner/smaller wheels will be even lighter and cheaper.I have F1R rims and they're rated at 25lbs a piece. I was looking at aftermarket rims for that exact reason. I understand unsprung weight lets the wheels get going quicker. The problem is for a set of super light rims + tires it's ungodly expensive. You pay for what ya get I suppose.
I think those were the ones I was looking at. Honestly I'm split between getting the 17's or 18's. I'm thinking 17's but I do like how the F1R's look on my car. I think I had it all in cart and it was something like $1,800 wheel mounted, balanced, and shipped. I didn't see a white option for any of the rims when last I looked. Could always powder coat.Not sure if you've seen by now but the enkei rpf1 is lightweight and should be less then $350 per wheel.

Tire rack also has all the weights for all the different tire specs for each tire so that's also something you can check out if not alreadyI think those were the ones I was looking at.

Thanks for the info!
So far the price is about $1,500 which is what I thought it might be with some decent tires. This is with 17's and about a 215 tire width. All things considered, do you believe this will be sufficient tire for the current setup? I worry if I go too skinny of a tire it won't corner as well.

Btw I immediately noticed the lighter weight of the wheels driving normally from a stop so I would 100% recommend it for a light car build. My car is otherwise untouched in terms of weight.
I'm not sure but it's worth considering that 215 should keep the steering feel light, my steering feels noticeably heavier with the wider track/tire of my setup. I think you should look at tire size feedback from people who actually track/autox their cars since I just drive my daily spiritedly lol.So far the price is about $1,500 which is what I thought it might be with some decent tires.

Those are my thoughts as well. I don't have enough power to require a lot wider tire I think. I'll look over some feedback from those autocross folks have.

My initial thought is that the tire choice would matter before the width though.
Hey I was wondering if you can help me with the srs light issue. Can I just unplug the airbag sensor and plug in a 2.2 ohm resistor without disconnecting the battery? Or would I have to disconnect and reconnect the battery everytime I check the connection?Another update:
I took out the stock seat in favor of a bucket-style seat from NRG. I purchased the seat bracket from redline and the specific brand is planted. The bracket itself weighed 8 pounds exactly and the seats were somewhere near 20 pounds with the side brackets so a total of 28 pounds give or take. I went the fixed route as to minimize expense and weight. These bucket seats do not have the airbags present that the OEM seats did so that further cut down on weight but I do have a SRS light on that I'll have to ignore or sodder a 2.2 ohm resistor into. Planted sells driver and passenger side separately so I'm waiting on the passenger side. Until then I'm rocking 1 seat.
How much of a weight savings is the aftermarket seat over the stock one?Another update:

Disconnect the battery when dealing with anything electrical. Trust me, would not be fun to have the airbag suddenly go off when you're messing with stuff. After you get the ohm resistor on you shouldn't have to do anything else and it should work like normal.Hey I was wondering if you can help me with the srs light issue.

I couldn't get a great measure since the seat is shaped so weird relative to my scale but it was in the 45-55 pound range so with my guess ~50lbs for the OEM seat including the brackets. 50-28 is 22lbs per seat saved so a solid 44 pounds in reduction isn't bad. When I was rocking the single seat that weight reduction totaled up to (50lbs + 22lbs = 72lbs!) not too bad for a simple bucket seat swap and great for track days with just one seat.How much of a weight savings is the aftermarket seat over the stock one?
