please dont laugh too hard but ,has anyone used sierra irs set up ( can the original bottom arms be used). anyone got pics ?

whenever this question comes up, i always answer it the same - i have, but its crap. very heavy and poor geometry. adds a bit of length to the car too. the subframe is the worse bit.

if at all possible id consider another layout. i just cant be arsed changing mine!

the Vindicator Sprint uses the sierra rear suspension "as is"

Robin hood and some Tiger’s use them also.
I use it and it is not much more heavier than a Live axle. At my car i’ve welded the Sierra subframe in the chassis. It makes the chassis more rigid.
If you want a light car, use the double wishbone principle. I’ve you don’t, put the (durable) Sierra ones in.You must adapt also the chamber. Because your Locost suspension is lower than at the original Sierra.

See my photo archive

easiest option for build is a book rear end with a sierra dif/axle and dedion tube imho

Vorn,

Don't use it! It's appaling, heavy and ugly as hell- with no offence meant to Joel or Dr-fastlane!

If you really need to stick with the Sierra back end then either design your own IRS (hard work to get right) or order a DeDion system from GTS Tuning or MK Sports Cars- then you'll have a high quality system.

Hope that helps,
James

The Dion-axle is also a really good alternative. If i had design my car again, i build it with a Dion setup. Beacaus it is easy to build and lighter.

Cheers guys . weight and looks dont mean too much to me at the moment, its a case of getting a car on the road . think its a bit harder to get VINS (MOT) in new zealand , so the less I make the better
