I'm still reading the rules for the SCCA class I want to run in (eventually) and some of the excessive weight shedding already done to mine may be outside of what's allowed. If you're interested in swapping doors and saving yourself the labour I think I can schedule a road trip.

When I went to the track for the first time this year after removing 150lbs out of my car I couldn't believe how noticeable the difference was. Not so much in straight line acceleration (although I'm sure that was improved too) but more so in the tight technical twisty back to back turns. The car seemed more "flickable" as if you could just rotate it and point it to where you wanted it to go. The chassis has much less weight and dive into corners so it was much happier to abruptly change direction and go where you wanted it to. The understeer also didn't feel as heavy if that makes sense.

*EDIT - that's a cool idea for the windshield. I was going to try and reinstall the OEM fan and heater core on mine.

Hmm, that might actually be a really god idea seeing as lexan isn't exactly cheap. I don't particularly want different coloured doors but at this point i'm not too concerned about looks. Mine still have all of the electrical hooked up, just no interior door cards.

IMO it is the best solution for windshield for a dedicated track rat. I contemplated keeping the OEM heater box for the defrost option, but it weighed way too much to keep around for a couple times of use. The heater wires from BW are extremely light and very effective. These are the ones I plan on using when need be https://www.bimmerworld.com/Safety-R...oster-Kit.html

That bimmerworld defroster is a game changer. I think I will use that in my Z31, so thanks!

Agreed, I was extremely happy to stumble across them online. Before finding this I never saw a good solution that actually seemed effective other than the heavy and bulky OEM defroster

I am probably at that point with the harness but this is new territory for me so my plan is to slowly separate the harness and remove what isn't needed. I eventually plan to go with a standalone ECU but I still need the OEM ECU and wiring for the throttle control, ABS, tach and spedometer so I don't want to mess any of that up.

Most of the wiring in the above pictures is likely now obsolete and I'm sure a lot of it will be gone once I clear through it all.

The SRS/Airbag stuff is all gone already but I'll inventory all the remaining wires and see what can be removed. I'm also considering removing the key switch and steering wheel lock since it's not going to go on the road ever again. Headlights can go too, I think, but they're already pretty light. Not much weight savings compared to steel and glass on some older cars.

agreed, I'm going to leave my lights in for now. I though about the steering lock and key switch but since I plan to tow dolly my car I think the steering lock with prove useful for the time being.
