My
JCW MINI is just shipping to me today, but I've been through modifications of 2 Subarus (WRX and LGT). You will kick yourself for not having done the mods sooner. Downside: aforementioned (always too late!) and never enough- it's like a disease. Get a taste of increased torque, better handling, what have you, and you'll soon be yearning for ever more!!!! But it's fun! Go for it!
