Carry the Weight, or rather don't...

Post by OlberJ »

Have a couple of projects banding about at the minute, and have a Mk1a just in which is going to become a tarmac rally car (not be ready till start of 2011).

Anywho's i'm wondering what weight people have managed to get Mk1's down to?

The cage will obviously add a bit back in but what sort of weights do the challenge cars etc manage?

950-1050kgs is the standard weight, correct?

Check whether there are any weight minimums, otherwise its really all dependent on how far you want to go in stripping the car out, obviously there's seats etc, there are carbon fibre elements. All depends on how far you want to take it, but stripping the interior alone will help dramatically, the firewall sound protection alone weighs a tonne!

Absolutely, it will be bare to the bones, even as far as drilling holes where able to. I'll check on a minimum weight but doubt we'll get that far.

Any ideas what weights they have got down to simply by removing parts/lightening?

Carbon fibre aint an option (for us) really.

Not been on the scales for a while so there's a degree of estimation involved but our mk1a should be somewhere just over the 900kg mark by now. That's with no cage and a 4AGZE conversion on an n/a gearbox. (The SC gearbox is a fair bit heavier). Not really spent any significant money on weight reduction, it's mostly been a case of getting rid of stuff that's not needed.

I thought it was a fair bit heavier than that?

Lowest standard weight quoted for a UK spec car was for the 1a at 1031kg

Knew it was somewhere around there. Obviously a bit more for a t-bar etc.

It's a sunroof mk1a i'm going to be stripping down before we build back up.

Hopefully get it under the 900kgs mark.

My track car i'm hoping will be a fair bit lighter than that, but that will be for good reason :mrgreen:

If you are going to use the car in msa approved rallies check out the blue book that you gety with your compertition licence this will tell you what you can cannot do to prepare a rally car.

Also check out the amendments to k37 stage rally regulations as from this year there are additional restrictions and basically special and spaced framed cars will no longer be granted an msa log book.

weight

Post by aw11rally »

We will have to put our rally car on the scales at some point. I'd guess it's around 900kgs, maybe less. For a start each door is 15kg lighter than standard.

I'd love to be able to lighten the doors. Theres so much weight there but TSS regs prevent cutting any metal out of them unless we fit a full cage first. I've gone as far as removing the central locking solenoids and most of the wiring. Only thing left that I'm allowed to do is fixed plastic windows and ditching the electric window motor and runners etc.
