To lower or not to lower... Now with Mach1 springs = lowered! Reply #15 – September 17, 2007, 08:00:21 PM Definitely lower it, it looks a lot better Quote Selected
To lower or not to lower... Now with Mach1 springs = lowered! Reply #16 – September 17, 2007, 10:37:48 PM OK, I cut the other spring. Looks good though the car is still higher on the passenger side by 1/2" :(Also, the drivers side tire ishiznitting the wheel well - 3 times already. I tried turning one of the rear springs 1/2 turn but it just made it worse. I think I will need to get a bump-steer kit, though the tire easily hitting the wheel well is my first concern.Any suggestions? Quote Selected
To lower or not to lower... Now with Mach1 springs = lowered! Reply #17 – September 21, 2007, 11:05:02 AM OK, the spring rate of stock springs is too low when they are cut. I am hitting the fender with the tire regularly now. I realized after doing some research that a lowered car needs a higher spring-rate to keep the tires/front-end from bottoming out. I think the recommendation of at least 600lb/in rate for a lowered car is about right. I found a used set of Mach 1 springs (600 lb/in) for a good price so I'm going to use these. These should lower the car about 3/4" to start and I will cut the coils to get the exact height I want. The Mach 1 & Bullitt springs look like a good deal for our cars IMHO. See the "Spring rate and drop" table I recently posted in Suspension for more info on springs. Quote Selected

Reply #19 – September 28, 2007, 05:08:40 PM OK, I got the Mach1 springs today and installed them immediately (took only an hour - I am an expert at this by now - lol).BEFORE:AFTER:BEFORE:AFTER - the drop is about 1" - 1 1/4" :I also measured the springs before installing them - this is the Mach1 spring versus the OEM spring WITH ONE COIL REMOVED!As you can see, the OEM spring is about 15-15 1/2" long before cutting, the Mach1 spring is about 13" long. The difference is in the spring rate.Oh, the ride is so far very nice. I am NOT bottoming out AT ALL now even though my street is being paved and is bumpy gravel. Also, I did not change the struts, but the replacement Gabriels that I have were always punishing - I remember getting them cheaper as the guy at NAPA said they had re-valved them in the newer model. All I can say is, they were too stiff before and now they work well with these new higher rate springs - my bumpy gravel road hardly felt bumpy at all after adding these springs which is a good sign.

Reply #23 – September 28, 2007, 11:24:49 PM Quote from: Sduneman3;179541Good info, I'm about to the process of Installing my 99' GT springsI will provide updates going forward, but so far based on first impressions, I will state that I believe that the Bullitt/Mach1 front springs (nearly identical) are a win-win fit for our cars. They lower the car just enough to get decent improvement in center-of-gravity without going overboard and yet they provide the increased spring rate that is needed when you lower the car to keep the fenders off of the tires. I am very happy with this mod!Let us know how the '99 GT springs work out! Quote Selected
