We have an 06 GT Coupe. Love the car. It's the 60's muscle car I couldn't afford when I was 18.
I want to lower the car, and instal new tires and wheels for summer cruise in's. i like the factory rake , but most of the lowering spring kits I see want to lower the back more than the front.
Assuming the following: 1) Car is driven by my wife 95% of the time (daily) 2) Want to keep the factory rake while lowering the car 1.5 - 2" 3) Want to maintain or improve the ride for daily driving
Questions: 1) should I opt for the coil over kit. If so what else is required other than the kit to make this pkg. streetable? 2) I have 18" std. wheels on the car currently. Should we go to a larger diameter wheel and tire pkg. I want to fill up the wheel wells, but I don't like the looks of do nut tires. 3) will i have to recalibrate the speedo 4) can you reccomend wheel width and backspace for the street?
Goals: 1) I want this to be subtle. No ouragous tire and wheel pkg's. 2) I want to maintain streetability. 3) When I drive the stang to a cruise in (rather than my street rod) I want my buds to salivate just a little.
Hopefully we can answer all of your questions in order.
1. If you want to be able to adjust the height of your Mustang then a coil-over kit is the ONLY way to go. The coil-over kit will allow you to adjust the height to fine tune your suspension. If you dont think you'll want to adjust the height... then you probably will not need a coil-over kit.
2. I would personally stick with 18inch rims or less. When you lower the car, those 18's will nicely fill up the wheel wells... without all the drawbacks of 20inch rims... like clearance issues, comfort, poor handling, weight etc.
3. You will only have to recalibrate the speedometer if the tires are not the same diameter as the OEM tires. You can calculate this here... http://www.stangsuspension.com/tirecalc/
