AE86 weights list
Righto,
Everyone knows that less weight in an AE86 is better. It's the welterweight punching above its weight right? But what exactly can you do about it and perhaps more importantly, what can't you do?

When we go online and start looking we find lots of posts that suggest that a couple FRP panels and we're at 850kg's. Some people claim that low 700kgs are possible with a full cage and serious cutting of sheetmetal. Lets try and see if we as a community can try and get an idea of how serious we can take these claims.

Over the years I've weighed some stuff as it went through my hands. Mostly suspension stuff for my models, but some other stuff too. Logic dictates that when we add up most of the important stuff we end up with the weight of the final car.

What I'm going to do is post some tables with parts, weights and where applicable weight saved. Hope you guys will chime in with some measurements you made yourselves. I will update them on a regular basis.

Could gain a lot by data on lightened flywheels, and data on weights of OEM engine parts (alternator, std plenum/manifold, 20V ITBs, exhaust mani)

F20C can get down to 185kg with money thrown at lightweight parts, but difficult to do with that heavy transmission.
1UZFE weight taken from a picture of an actual 1UZFE hanging from a scale. Idiots without proof of lower weight do not have to apply, yes they are that heavy, no they are not made of fairy dust.

Why the reservations? You can edit your first post any time you like Dumb question

Bit odd to calculate the weight of the rear fenders... they're part of the unibody.

Thanks for posting these weights, it really shows not only what
is possible but also that the work and cost is worth it.
Getting on for 100kg saved overall including interior parts and
underseal etc ?
