What made you choose this particular product?
Just looking to replace my blown stock rear struts. Not sure how these OE replacements will last but I don't want super stiff struts for rally racing.

What made you choose this particular product?
Good kit. Rides better than stock. Looking back I would have tried a coil over. Not a knock against these but they aren’t amazing either.
Is this your first time buying from this brand? Did you consider other brands?
Yes first time. Have set at 1.75”
Was it easy to install? Any installation tips that will help others?
Paid local garage. They put the rear on upside down so I flipped those myself
