roadster vs locost?

...and a well setup Roadster will run rings around a standard locost.

All depends on time and cash.

Best we tell all the race teams in the world + F1+ the car companies that they are all wrong and to put live axles back in the cars cos they are bestest

Doesn't matter how the drive is transferred to the road, whether a live axle, IRS or Dedion.
The important bit is geometry so it actually works.

Cant accept that you can have something as heavy as an axle which weighs as much as the back end of the car as unsprung weight. All ok on a billiard table race track but show the car some shite roads and it will skip about all over the place. I have driven both and thats exactly what the live axle does, its just not compliant over potholes etc.

not much between an independant and a de dion (caterham). Live axle ok for track use.
As mark says though the geometry has to be right.
I haven't seen any graphs of the camber gain vs deflection for the haynes.
The rear is the easiest to get right, it's lot harder to get the front right especially with the constraints of the front uprights.

For me it will be about on road fun with the odd track day, it should be a laugh what ever, as long as I have enough power to pop the back out for a bit of controllable fun I'll be happy!

If I'm unhappy down the line I'll look at changes to the geometry.

to the OP, i'm sure there are many locosts running with independant rear ends. That way you'd get the best of both

Thanks for the input so far guys

To add to the debate, what's people's thoughts on the mx5 based roadster vs the sierra based roadster?

Are the mx5 components lighter? I know the Mazda
Engine is somewhat more powerful than those stone age pinto's.

But, I take it the mx5 route is more expensive and complicated?

The wiring is probably more complicated if you take the MX5 route.
The rest isn't any harder, and in some ways it's easier as you don't need to make new rear uprights, or add those mushroom things to the front ones.

Not sure it's any more expensive either. The donor might cost you slightly more than a Sierra but MX5 parts are still in demand and you can cover the cost of the donor (and even make a small profit) selling the bits you don't use.

I'm not sure the wiring is any worse with the mx5 compared to the sierra. I've removed at least 2-3 bin bags of wire from the sierra loom that was either redunant or just too long and had to be shortened.

We know that
