How much horsepower to expect and perhaps what category restrictions you might be limited too. For the hidden performance its for those that want to either look stock for just fun or to hide it from the dealer or anyone else. These results might not be exact , but these are tried and true real world prices and dyno's that provide the info. Also the parts used are just some of the parts that can be used. Of course there's more to add on to some or some can skip some and use some of there own. These parts were selected by there availability and popularity. More exotic parts and others weren't used since they basically don't do much or are really hard to get. As For Suspension Goes its simple....pay more handle better. Stage IStage IIStage IIIStage IVStage VSuspension PlanSpring Only $100-200Spring and Shocks-Non Adjustable $400-800Spring and Adjustable Shocks $700Coil-Overs $1200-1500Full Race Coil-Overs $1500-2200Explanation - About the suspension changes and difference in levels.Quick easy install , some kits lower too much for looks and you get a unsettled ride which isnt good for high speed bumps. Stock shocks will soon go.Now you have something to work with , even though they might be out of synch.This one you have a lot more to work with , you can adjust the shocks at least to try to match the springs and the car better. Yet still probably wont have a lot of travel, and you might just get a product that doesnt go well togetherThese systems if really made for your car handle the best can be tuned like the stageIII but also have a bit more spring rate, ride height and travel. Which can help a lot. Street / Drag or CourseAgain just like stage IV but probably a higher known competition name or perhaps the shocks will have their own reservoir....which sometimes are controlled electronically from the car. Brakes , bigger better stronger....pay morestop quicker.

Just make sure their not some crazy kind that need to be real hot. Also good to add race/dot4 brake fluid.Great for the street, possible new caliper, might need bigger rims. If your not really going fast then this might be overkill, but then again you might like safety. Also consider changing lines.Made for high heat all the time applications , more emphasis on cooling and anything to do to slow down. This is because on the track you are on the brakes a lot. The street you brake a bit and then cruise. Just like before but Anything from really oversized rotors & dual calipers .To materials made to handle anything. These kits will make any street tire the bottle-neck for braking faster.
