Lowering Springs

[Minn19]

Are the R springs actually lower? I was under the impression that the reason why the R was physically lower was because of the tire height differences. 315/30 vs 305/35 and 305/30 vs 295/35 is kind of a lot.

I thought the same thing. Also thought it was only the front springs that are different.

They are all different according to the part #'s. The R springs are shorter and the sidewall accentuates the ride height.

Thanks, I either read the manual wrong or got it mixed up with the regular GT350 track pack equipment.

The front springs on both the Track & R model are the same.
The rear springs are rated at different lbs. The R is heavier than the Track.

Look it up in the specification of the supplement manual.

I am corrected:

Front -spring rate - 194 lb/in - Track Pack.
" " 240 lb/in -R

Rear -spring rate - 914 lb/in. For Both Track Pack. & R

No mention of height of springs for either one.

Tires Sizes :

Base - 295/35R 19. Front. 305/35R 19. Rear.
R- 305/30R 19. " . 315/30R 19. "

Hey Everyone. Placed my order recently and one thing Ill want to take care of quickly is the ride height of the GT350. Nothing drastic but to me it needs to come down a little bit. What are the lowering spring options out there? I did a search but didn't find much.

Thanks

Hey! Welcome over to the dark side. You will appreciate the GT350 if the M3 didn't do it for you. I agree the ride height is a little high, but the suspension setup is really dialed in. I've replaced the suspension on all my BMWs but I don't really want to touch this one. That said, if Ford Performance comes out with a complete kit, I'll probably bite, but I'm not just going to throw a set of coilovers on this car.

R springs are shorter, check the photos and notice the fender gap is pretty identical despite the R having smaller tires.

That said they are .25" shorter, not going to blow your mind.

Also the R has stiffer front springs, and identical rate rear springs. The rear gets shorter arms on a same diameter roll bar to make that effectively stiffer.

We will see, if I do camber plates, I'll switch to R front springs since they are stupid cheap from Ford even at full price.

If I recall correctly Ford was going to be developing lowering springs for the 350. Just be patient and wait

I can't wait till they come out. The thing sits up way too high. I'd like an inch drop all around.

All the aftermarket springs for gt will work on the base gt350 without the magride..

As far as gaining any performance enhancement other than lowering the car, who knows?

I am in the process of installing base gt350 shocks and struts on my 2016 gt with Sportline springs. they bolt up perfectly fine. The front struts on the base 350 is mono tube and has a longer shaft. Also, the base 350 struts do not have the big dent on the strut body like the gt models. So running 350 struts with factory gt wheels you will rub on the strut housing. I am running 12mm spacers and Mrr 350 wheels without any rubbing issue.

Will see how the shocks and struts perform with the sportlines once completely installed.
The front 350 struts are identical to ford racing struts. Compression and rebound are also 99% same as the FRPP struts.

Definitely sounds like the best plan is to wait for the Ford Performance. Are there any good forum resources who may have the skinny on ETA?

I'd be VERY cautious to put any kind of lowering springs onto a car with Magnaride shocks. Unless they are specifically designed to work within the travel rates of the Magnaride shocks (which they probably aren't). I wouldn't suggest ANY springs.

ALL too often, people are quick to just slap a set of lowering springs onto a car because they want it to look nicer, but have no regard for functionality and how the car will work once making those modifications.

They call it a suspension "system" because it really is a system. Every component in the suspension is designed to work with everything else to give you the desired performance in every situation. If you change just one of the items in the system (springs), but don't change coinciding parts within the system, you will get your desired lowered look, but every other part in the system will be more stressed, perform more poorly and wear/fail more quickly.

Guys with regular old Mustang GTs do this all the time, and it's a shame, but if you have the money to buy a GT350, you owe it to yourself to make the CORRECT choices when changing parts in the suspension.

If Ford Racing is to offer a kit, it will probably come with different shocks/struts, too, and that is what you would want to look at - NOT just springs.

I did the entire Ford Racing adjustable handling pack on my Bullitt, which has adjustable shocks and struts, springs, strut mounts, jounce bumpers, adjustable sway bars and adjustable panhard bar. That is really the type of kit your GT350 deserves. Not just a set of lowering springs.

Mag ride isn't anything new. Chevy has had it for some time. They throw on lowering springs and doesnt seem like any issues have been reported.

Just get the Swift Spec R springs. Those will be a good match when you consider they're pretty stiff buggers.

Just buy some 20" wheels and call it a day. They'll fill up that gap in your wheel wells without messing with the suspension.

The diameter of the wheel and tire are likely to be the same, if not very similar to stock with the 20". The wheel gap is what needs to be reduced.
