First, hats of to my friends at FD for taking the time to respond in elaborate detail the science behind their setup. I don't see any other manufacturers doing this.

I am the result of a FD sport spring setup. I did extensive research on this so I can save you all a lot of effort. There is no comparison here. FD is the only tested solution to lowering our car. They have this dialed in. My car was set up to perfection. Look at the stance! The drive is equally as perfect. No scraping. No issues. Quality is top notch. You won't find a better fitment so take advantage of their holiday sale and pull the trigger now. While your at it look at their DBW, Big brake kit, rear spoiler, Sport Exhaust, etc. I have it all and love it! Thanks FD!

FD,
Does adding the springs affect the Skyhook's suspension ability to work properly? Or does it just give a stiffer feeling in "Auto" and then an even stiffer feeling in "Sport"?

Rzundel,
Your car looks great! Any input on that? Now that I have my wheel spacers on the car, I feel like the fender gap is even more noticeable.

Thanks

Thanks for your comments. In my opinion to get your car dialed in you will want springs and spacers both. When your wheels are pushed out with spacers your gaps will be more noticeable. What this really exposes is how tall the factory sets the springs on our cars. Especially in the rear. FD springs will correct this. And yes it works well with Skyhook. Nothing changes with its function with dampening control. Same as stock.

Love how your car looks especially the wheel fitment! Do you mind to tell me your wheels spec since the OEM wheels sit too far behind fenders and the wheel gaps are huge! I'm thinking about to get a new set of wheels so I would really appreciate your input:thumbsup:

HRE has my exact wheel specs because they built me a custom set. I will tell you that I am running a 21x9" up front and a 21x13" in the rear. That includes a 355/25/21 tire in the rear. That is one mean looking profile from the rear. Fitment is perfect with no rubbing. Works great with the springs FD built for my car.

The problem with the GT, is that the front overhang is significant compared to most other cars. Especially with the MC Strad front bumper, the lower lip hits almost everything, and my car has all stock suspension. Where my F430 is a lot lower of a car, the front overhang is not much at all, so the car hardly scrapes. The GT is a very difficult car to drive for this reason. Lowering the car doesn't help the issue.

Interesting. I've never had an issue with rubbing. I have skid plates installed on my car that have been barely touched. I have much worse problems with my Porsche 911. Funny we have different experiences.

I'm going with the recommended/standard FD lowering springs for my 2013 GT sport convertible. They just arrived with just about everything else FD sells [emoji3], took full advantage of the holiday sale! First item installed, wheel spacers, look great. I want to stay with my factory 20" trident rims (to be finished in gloss triple black), but going to install wider rubber. Thinking in rear 315/35-20. Taller than stock by about an inch. Since the FD springs lower rear 1", I'm thinking this setup would reduce my fender wheel gap by about 1.5". Thinking similar approach for the front. Should help with clearance and get the lowered stance look. Thoughts?

Congrats on your recent FD purchases. You're going to love their quality and improvements to your new GTSC.

As for the tires you need to proceed with caution. I applaud you wanting to go wider in the rear but you have to be very careful with the ride heights because they affect many things that are electronically controlled by the car. You're always best trying to stay within the specs of the total rolling diameter set by the factory and if you do make changes you need to stay within the same ratio front to rear on total rolling diameter. This way you will avoid setting off error codes. Hope this makes sense? Just work with someone knowledgeable in this area to avoid problems. Good luck and post photos when complete.
