He also has more traction problems with less weight in the back. Once you reach a level where more power cannot be achieved, then weight becomes more of a factor. I don't think it is worth the sacrifice of comforts. So far what I have found is that though weight reduction helps especially off the line, you can usually overcome the weight more easily with more power with maybe adding a couple lbs of boost more. He is obsessed with weight reduction to an extreme level and my goal is max power. We are sort of total opposites(I have a G35). My friend got his 350z down to 2900lbs, but he removed everything in the interior except drivers seat and gauge cluster and fabbed up OEM chassis bracing parts replacements from aluminum. Weight reduction is definitely possible if you can live without AC or an interior. If not your $400 battery will be no good in a year or so. I have a dual AGM setup in my 4runner but I have to run a voltage booster to supply that higher voltage and still keep it on a NOCO battery maintainer when not in use for a few days. Remember that Lithium and AGM batteries usually take higher than normal charging voltages and if you do not supply that it usually kills their overall life. Some people could use actual WeightWatchers. But we will see what the aftermarket comes up with. The GRC exhaust looks pretty simple with minimal mufflers/resonators so not sure how much lighter an aftermarket system would be. ![]() The battery being in the trunk is optimal for weight distribution, but its still pretty heavy…lithium batteries are pretty good these days and will save about 25-30lbs. Pretty popular on a lot of hatchbacks is Rear Wiper delete but it’s only like 5lbs and then you dont have the ability to wipe snow/road spray off if you drive in adverse conditions. I hope once people starting getting their GRCs, they can post weights of interior components on this thread. Some decent weight can be saved by depending on how much you’re willing to take out/how much livability you’re willing to sacrifice… Rear seats, tire repair kit/tools, door panels, headliner, sound system, carpet. This page has a good list of weights of many of the stock GRY interior parts, most of which presumably will be similar/same ballpark on the GRC. Maybe the aftermarket will come up with other lightweight suspension components (a-arms, etc) as well. Aftermarket 18” wheels in the sub-20lb range are available which is a great way to save some unsprung rotational weight.Ī few pounds might be saved switching to aftermarket coilovers, though that Willing be the primary reason to upgrade to them. The GRY wheels are 23lbs (standard cast) or 18.25lbs (Forged BBS Circuit Edition) … I expect the GRC wheels will be a bit heavier maybe 24+lbs since they are wider at 18x8.5 (vs 18x8.0) and cast. Lightweight or modified bumper supports/crash bars might be able to cut a bit of weight, though my understanding is it’s pretty lightweight aluminum. ![]() Nothing about the fenders being aluminum in the press release but the GRY has them so maybe. Most of the body panels are already lightweight material such as the aluminum hood, doors are aluminum(according to press release), rear hatch is plastic, and carbon roof (at least for CE…). Ideally trimming it down to under 3000lbs would be a good target. The weight of the stock GRC is said to be 3250lbs…which isn’t crazy heavy but it’s a bit porky for a small car. Discuss part weights, weight reduction options, etc. But i figured I’d get this party started. A bit premature when none of us have a car yet? Maybe.
