How good is the Haynes IRS?

[Antnicuk]

Hi All,
I have just signed up here although i have to confess i'm not building a Haynes car, well not a complete one.

I have been recommended to this site by one of the Locost builders.

I have a Stylus with an Atlas Live axle. I am considering changing to IRS and wondered how the Haynes IRS compares to other kit car's IRS in terms of performance. The car has limited road use but mainly track days.

I want to try IRS to see if it copes with the power a little better.

I will be making the diff carrier to attach to the chassis but will use the measurements, wishbones, uprights etc from a known (good) system.

Is haynes the same design as the locost or any other mainstream design.
