Do you have to cut the factory bump stops with Tein S Tech springs? I heard you do with Eibachs, but Teins dont drop the car as low as them. What kind of bad things can happen if you dont cut them?

 

I can't tell you whether or not you'll have to cut your bump stops







But if you hit them while cornering hard, imagine suddenly replacing your outside spring with a brick. Roll stiffness jumps through the roof, followed by your insurance premiums.

 

I have Teins and I cut my bumpstops down but not by much. No issues.
