slow track build
I'd like to introduce myself. I've posted a couple times. yaddy yaddy yah. I bought my 85 GSL back in October of 2010. It had been sitting for 2 - 3 years in a garage after the lady's husband died. He had had the original Mazda dealer do all the work. I got all the service records and everything has been done. Even the motor was rebuilt at 120,000. It currently has 175,000. New drive shaft, shocks and springs. Everything. The dealer took them for a ride, that's for sure. So anyways, I drove the car for about a year learning the advantages of rwd after leaving my fwd vr6 turbo car behind. Fell in love so it points me at this point.
I am so obsessed with stripping the weight out. It started because a lack of funds due to getting married and trying to move from VA to FL. This past summer I did everything from porting the intake, did the whole Sterling DIY carb mod, chopped the exhaust off. I have been running a side exit for a couple months now. (I try and avoid driving the car long distances at all costs now haha) Recently I stripped the car out. The engine bay is down to the essentials.
The interior I have removed everything but, the dash shell, the instrument cluster, and center console.
Prior to chopping the exhaust and stripping the interior the car weighed in at 2240. (with AC still in car)
After I had just removed the spare tire and some other small bits it weighed
2460.
This is all with 1 gallon of gas each time and the same scale.
Now with the interior stripped, engine bay stripped a bit more, and no exhaust I am pending a weight.
I am at a tipping point with the car though. I very enjoy the sport of drifting quite a lot, but I also love track days. So for now, until I can make up my mind the car with just get lighter and lighter.
My plans for the up coming months. Remove hood and do a single layer of fiberglass to keep the rain and dirt out. (it will be super flimsy but it will be secured in either 4 or 6 places. Maybe even a center mounting hood pin or something. The rear glass will be getting replaced with lexan this summer.
Wheels, I plan to run adapters from 4x110 to 4x100. I am undecided about wheel size. 15s look the best, but lack tire choices. 16s still fit my style and have quite a few more tire choices. 17s look terrible but are best for tire selection.
I will be doing aggressive fender flares, a rear "deck lid spoiler" and a front (maybe a rear) splitter at the same time as this.
Right now the car has,
tokico blue shocks,
ground control 350lbs front and 200lbs rear springs The rear springs are from a VW
electric fan, sterling carb mod, intake ported (up top, not by the runners) all the emissions stuff removed, exhaust fully removed, corbeau seat, 4 point harness with factory seatbelt. (will be switching to 5 point) some wooden racing wheel. (bought the set up for the hub adapter but love the wheel now) car is majorly stripped.
Within the next few weeks it will be getting a roll bar that attaches in 4 spots, water temp, oil temp and oil psi gauge set up, and ordering a RB header flange to make a custom equal length header. If I find thin walled tubing that's not going to weigh much more than the current exhaust manifold then I will be extending the exhaust back some.
That's a test fit. looks much different now. I will get a current picture up this evening.

nice car! mine is - interior too and its LIGHT, i haven't weighed it, but the IMSA cars in 79 were 2020 with full glass and all steel.
oh yeah rota makes wheels in 4x110, the RB comes in 13,14,15 and maybe bigger, so you can skip the adapters. in a road race car, you'll want the 13x8, with like a 225ish tire. shorter is better

When you say full glass and steal, you mean no body panels were replaced with fiberglass or lighter material and no glass was replaced with something such as lexan? The goal is to have the car as light as possible, number wise, it would be around 2000. Give or take 50lbs.

"For rode racing I'll defiantly be using a wheel that bolts up to the hub. Unnecessary risk with the adapters. I'm fine with a 13x8, especially for weight, but what about tires? I thought there was a 13" tire crisis".
I think the crisis really only applies to "street tires" Kumho and hoosier still make tires in the 13" in a race tread
225 50 13 Hoosier A6 and R6. Kumho V710 in 215 50 13

there is an FB that shows up to sevenstock, and its all stock body and trim on the outside, with lexan windows and no interior (i mean no interior!), its 1900lbs.
the GTU cars in 1979 were at 2080lbs with glass windows big giant wheels and tires and a cage.
