radflo extended coilovers 2.0????????

so i am looking to get these for my dads 2nd gen but my question is will they hit the uca at full droop. and if so is that why they say you need new uca's? the 2.0 version

 

I'm also considering getting some radflo's while Metaltech has them on sale. Does anyone have any reviews on them? I searched but only seem to come up with fj or 4runner people using them. Anyone have any other suggestions for a 2.0 shock that may be comparable?

 

That is part of why you need new uca's. You won't get the full droop though without a uniball uca. The new arm also helps gets your alignment back into good driving spec. You can run a 2.5 without hitting.
