I have been talking with Jeff about trying the Formula Dynamics springs on my 2007 Quattroporte.

Anyone out there running these on their QP? If so, what are your thoughts? Do they make a significant difference? How long did they take to install? How much did you lower the car ultimately with the springs? Did it look "too" low? Would you recommend them?

Thank you,

Just installed the springs, dbw, x-pipes, brake pads, spark plugs, and air filter from FD. Man do I love this car even more now. Handles like a dream, the QP just hugs the road. Shifts are crisp and throttle is super responsive. Car is a bit bouncy now that I slammed it. There is virtually no finger gap all the way around. Ill take some pics when I get a chance.

Thanks for your reply. What do you mean though by your statement above? Did you lower it a lot? Too much? Are you saying the car is now bouncy with the springs?? I am confused by that. I was hoping any "bounciness" would go away.

Thanks,

I lowered the car a lot. Close to a 2" drop all the way around. I'm pretty sure the bounciness is caused by the extreme drop. From what my installer told me. With just the springs installed it lowers the car about an inch all around. It wasn't aggressive enough for me so I told him to lower the car as low as possible without hurting the suspension or to have any rubbing issues. Once you see a picture of how low my QP is you will understand what I mean. The car handles like a dream though. Feels much like a coupe instead of a huge sedan.

I assume your car has adjustable lower perches on each of the shocks then? Otherwise, you wouldn't be able to adjust it down further I think. Mine are fixed on the 2007 Duo that I have. Apparently they changed it from adjustable to fixed to prevent tampering with (like you did!) which can make it too bouncy and then wreak havok on the shocks and blow them out prematurely (that's what I've been told anyway).

Anyone else out there used the FD springs on a QP??

Yes i have the adjustable skyhook suspension. From what Jeff told me, And from what the instructions said that came with the springs. The drop on my car is completly safe as he has lowered some other QPs much lower. That's the whole reason why I bought the springs was so that I could safely slam it without damaging the skyhook suspension. For reference the car is a lil bouncy , nothing like one of those Honda kids rice burners.

Maserati reportedly had problems with customers lowering on the factory coil overs for the QP. Customers felt that if the adjustment was there than it should be fine. However, as I understand it, they changed up the design to restrict this.

Lowering on our Sport Springs should not be a problem and we have had several customers go this route without any troubles.

Best Regards,

I have the FD sport springs on my GT. Corners well now and it's not too stiff of a ride. If you're just crusing around they don't feel much different from stock. I also lowered the car a bit after the sport springs were installed.

I have the FD springs on my 05 QP (I think I was Jeff's tester). At the time, Jeff had two choices. I went with the stiffer of the two and lowered the car about an inch. I was encouraged to drop the car more, but I couldn't deal with the look and was concerned about clearance issues. Springs and lowered ride height are a significant improvement over stock. The car used to wallow quite a bit before, but now feels much more solid and well balanced - handling is very neutral. Speed bumps, however, are a bitch, and passengers are less comfortable. You might try lowering the car on the stock springs and see if that gives you the combination of ride quality and handling that you want. If not, you can install the FD springs.

Thanks geshaghi for the reply.

Can you please elaborate on the comfort issue and speed bump concern. How bad is bad? Would a spouse complain in the passenger's seat? Is it rocky in the back seat?

If you wouldn't mind posting a couple pictures of your car, showing the ride hieght front and rear, that would be VERY appreciated! Total bonus would be a measurement from the edge of your rims to the wheelwheel, vertical in line with the center caps. What size rims are you running?

FYI, my car (2007) does not have adjustable perches on the shocks, so I can't adjust the ride height manually. It has to be done with calibrated springs and spacers. They changed the QP shocks to fixed perch so that people wouldn't mess with the ride height manually as the stock springs are not set up well to allow for lowering (they get too soft and mess with the Skyhook calibration from what I've been told).

I do have a question about the springs...with the skyhook, is normal mode more like sport and sport is just more aggressive than it was? Not meaning to thread jack, just thought I would shoot a quick Q in there...thanks LOL

trygve11,

With the car lowered and stiffer, I think the speed bump issue boils down to just slowing down a bit more than with the stock setup. You may need to roll over the speed bumps instead of driving through them from my experience.

There are pictures of geshaghi's car on our website (Black QP): http://www.formuladynamics.com/products/qp_sportsprings/qp_sportsprings.php

MaseratiSSGT, In general you're right the normal mode with the FD springs is similar to the Sport mode with the factory springs except that you'll still benefit from the reduction of body roll, diving on brakes and lifting on throttle. When you switch to Sport mode from there, the handling improves further.

Best Regards,
-- Jeff

Jeff is correct, you just have to slow down depending on the nature of the speed bump. My wife prefers her plush Bentley Arnage over my radical QP, not solely due to ride, but also because I have the Larini exhaust (loud), but her car is like driving a feather bed with wheels, so the comparison isn't fair. If you're in the area (Los Angeles), I would be happy to take you for a spin. The ride quality is probably a bit more aggressive than an M5, not as aggressive as my 996 Porsche with Bilstein PSS9 suspension. I can't imagine going back to stock. The car really feels much more solid and planted at speed (even in a straight line) - before I felt like my back end was unstable. Now if Jeff could only come up with an infinitely adjustable skyhook mechanism....
