Should I do it??
 

I have a zr2 and have been wanting a little more lift but not too much, scanning my local online ads and found this. Should I do it??

I believe that is just the RC 2.5in lift. Some members on here have it, not many though.

Well since you have a ZR2 you would only get about half of the lift... is the $425 worth 1.5 inches? IMO no, but its up to you. Ha have a 2000 ZR2 with short Add a leafs and a 2in body lift and have shackles waiting to be installed. 2 inch body lift much cheaper than $425...

Oh ok then Ill pass. I have never lifted a car so I am not sure on whats a good price

You could always get shackles for not much ($40, or even $20 for auto zone cheapies), and crank up your t-bars for free. But then it'll start wearing out front end components quicker.

get some 2" shackles off ebay or such. torsion bar lift 1.5" above stock.
that is the cheapest and most common lift option. as long as you dont go crazy with the torsion bars you will be fine.
