How do the bushes in Hardrace rear arms compare to Whiteline?
 

I can't find any info on hardness etc. of the Hardrace bushes. I could get a set from a mate fairly cheaply (although they are widetrack items and my car is a classic so need to check they'd fit ok. They are the adjustable type).

I am using Whiteline up front on with the ALK and the wishbone bushes. I don't want a mismatch front to rear so need to find out. If they aren't as good then I'll go Whiteline and stump up the extra.

Someone must know or have an idea?

Cheers, mine's a track car and running Whiteline ALK and bushes on the front wishbones so I'm really trying to figure out if mixing these with hardrace rear arms would be a bad idea or not. I don't want to have it noticeably harder up front than at the rear so should probably stick with Whiteline but thought I'd put it out there and ask.
