I have IRS rear end with drums. I would like to go to disc brake.

What are people's thoughts on a kit like this?

Interesting. Wasn't aware they were empi brand.

Are these any better?

If you are not on a budget the CSP are ok, the CB pefomance are nearly identical and are less than half the price, also they have been already approved for use on the road in Australia, i have a rear set on my ghia with the approvals.

Jigga you have listed the same brake twice, yes they are Empi, you can tell by the caliper bracket stamped out of a old jam tin.

Thanks for that
