Yes they make them for IRS cars. I ordered the set ( f&r ) but I only put the front one on because in order to put the rear one on it looks like you have to either drop the fuel tank or swing the irs down and I haven't gotten around to that yet but I'll likely do it this spring.
Impressions, I like them and the front seemed to help tighten up the front end although I have to say I put in springs, shocks/struts and C/C plates at the same so it wasn't just a pure impression. I didn't really think they were that much heavier than the stock piece especially considering it was thicker but then I didn't really weigh them.
