weight removal from bum!
Turbo Mini Forums

after removing as much weight from the rear as i can (as its the part i am currently working on.

So far i have removed the subframe to replace as its now past its use by date

The rear has got superfins, alloy subframe mounts, light weight exhaust, carbon parcel shelf, perspex windows, i have also fitted today a fibreglass bootfloor and i am waiting for my alloy tank

I will be lightening the rest of the car but focusing on the back at the moment

I plan on lightening and seam welding my rear subframe (new one) as well as fitting a fibreglass bootlid

I do not want to change to a rear beam and not want to fork out loads of money on radius arms just wondering if there is anythini else that i can do

Done anything to the rear valance? Attacked it with a hole saw? Reduce weight and drag?

2012 Avon class c 2nd place 13.8 @98mph

Can u get rid of the valance and put a rear diffuser on?

The turbo build has finally started

yes think ya can get rid of them to put a diffuser but think my exhaust will get in the way,

I forgot to say my valance is rotton as well as my closer panels so i am going to remove the closers and just fit a fibreglass valance with holes

sorry double post

Why would you need to fork out loads of money for rear arms if you went for a cut down subframe arangement?

cut down? Like a rear beam? That would mean i would need coilovers and i would prefer to keep my current arrangement

It's the radius arms that are the heavy bit on the rear subframe. That's why I have a nice pair of KAD alu rear arms waiting to go on my car (if I ever finish it).

oh, so done pretty much all i can for the moment on the rear

Also, you need the valance closing panels if you are having a standard subframe as they form part of the structure that attaches it to the body. No MOT tester worth his salt will let it go through with out them.

You could just have a regular shit, that would loose you about a kilo a day

There are a few places that a rear subby can have holes, you could remove the rear section amd replace it with some tube, then mount the exhaust abit higher and fit a diffuser if you wanted

Searching is all you need on TurboMinis

i ground and drilled the standard rear arms 18 years a go, managed to remove 2lbs off each,

I have seen pictures of standard radius arms with lots of holes drilled in them. Can't find the picture though but im sure it was one of the European guys.

You would at least save weight this way removing all the excess grease thats in the arms as a resut of split grease tubes
