I'm looking for some 1.9" coil springs for my protech shocks. I see them listed in the protech site at £25 but rallydesign sells them at £16. Is there any difference in quality? or I should save the extra $$$?

Thanks!

Cheers

I have RD springs, seem ok to me.

should be fine, the RD ones might loose their paint / coating earlier...maybe already after 1 season.
