They have a poor height adjustment system compared to everything I named above and cost as much or more than at least 2 of the 4 sets. The TEIN RE is the lowest on the TEIN line that adjusts height independent of shock stroke which is very important.

Pillow ball cattaer is terrible. The worst is on TEINs. JIC and Zeal come with solid upper mounts with rubber bushings making the noise MUCH less which improving the upper mount style. The ZEAL and JIC's have this mount included in their kits. TEIN requires you pay more for the pillow balls. I don't think this is the case for the exspensive TEINs but as mentioned the noise is aweful and the gain is minimal
