Because it is taking so long, and because of the group buy that has been going on for a long time they have gained a lot of negative opinions on the forum, and now all responses about anything gtm are all pitchforks and torches. If you only want to do supercharging the GTM kits have consistently mopped the floor with the stillen kit, but it has taken months for guys to get their kit. So if you choose to order take it slow, do upgrades on the rest of the car in the mean time, and DO NOT take your car apart or schedule the kit install until you get the kit.

Edit: now as for the actual intent of your post if you have a manual the whole clutch hydraulics system is utter garbage and will try to strand you somewhere, especially with a stiffer spring in the clutch, the diff bushings in the rear end want to explode, get an oil cooler with whatever kit you do order, a better radiator also helps. beyond that it is just gauges, and things like meth or e85 conversions. It seems so far that so long as you stay around or under the 550hp mark it will last a while engine wise until some random shiz like blown gasket happens(which also will happen bone stock randomly to unlucky people ask me how I know)

Also take cosmo's opinions about gtm with a grain of salt since he apparently managed to be the only person on GTM's do not sell to list lol.
