You gonna thank me for that tip.
Anyway look at this and don't mount parts like this if is really necessary. Those parts lifting your car in about 20mm 1 Inch 1" or little more but then your wheel geometry sucks:
When you buy professional kit, you need to change also shocks, springs, mountings. When you buy super lift kit you gonna get new frame for that - but this is really awesome, this is gonna lift your car about 3 to 4 inches. (3" - 4" , 30-70 mm). And you gonna get safe, high, and good driving car.
This yellow frame in pictures you get with other parts. In front and back. Just google it.
Ebay or allegro or finn. You can also buy from another country.
Just DO IT RIGHT!!! Thank YOU :)
