Not that I am making huge power, but with the Eibachs the launches are smooth. Hell, they were smooth stock. I have launched hard over 100 times, with 10 of them at the track. My tires arent the stickiest, but a huge improvement over stock. I think you need to worry about the axles when you start making serious power and are able to put it down and have the ridiculous wheel hop that has been mentioned. I am more worried about the clutch. I dont see that getting trashed anytime soon either though.
