Springs and Shocks help!

OK guys, i have a 99 mustang V6, planning on swapping engine or supercharging in the near future. Dunno if this matters but i have 17 inch Cobra R rims 9" in front and 10.5" in the back. I have been researching, and found Competition Mustang Steeda Springs and Bilstein Shock & Strut Package. Has anyone had any experience with these? Do they perform well? And will it work well with my future modifications. Thanks

Steeda springs are good but don’t expect much of a drop. Bilsteins are some of the best shocks you can find. H&R race springs are great and will work with any of your future mods. Their spring rate is comparable to the Cobra R so if you went to a 5.4 you wouldn't have to worry about swapping them out.

Bilstein definitly (although Steeda is alright with springs). If you wanted to get springs that have a good cost to value ratio, you should buy Skunk springs.
