Let's talk ride heights.

[strengthrehab]

Setting car up for next year.

2016 Mustang GT
305/30/19 tires
Coilovers (divorced rear with MMI adjusters)

Trying to get a ballpark for ride heights.

I measured my wife's stock gtpp

From bottom wheel lip to fender is
25.75F and 25.5 rear.

Mine is 24.5F and 24.75R

From pinch weld I'm at 4" front and 4.75 rear. Almost seems like I should bring the rear down about 0.5"

1. Similar cars...where do you reference measure for ride heights (bottom wheel lip to fender? Hub centerline to fender? Top lip to fender? Pinch weld to ground?)

2. Anyone wanna share values?

Trying to learn here.

Thanks and Merry Happy Whatever you celebrate.

I’m a bit surprised the FP350S owners manual doesn’t include any guidance on ride heights. For the S197, I used the Boss 302S setup guide which had detailed info on ride height, and the proper sequence of processes to get the ideal baseline setup.

Check out the @steveespo build thread - some useful information there on ride heights.

Ken, from wheel bottom go 24"F, 24.25" R then start the corner balance. You will end up cranking the left rear up a bit and the left rear up a bit less.

these measurements for 18 or 19 inch wheels?

Another comment to throw out there is how are you using your Mustang, Autocrossing , Time Trials, Road Racing , etc.? This is important because depending on the Class you are running ( if not just HPDEs ) you need to find out what the rules are for height in that area. A good example is a past customer wanted to run F Street with his Mustang, but he found out on getting to a Divisional Event his car appeared a bit low. Being new he was unaware of the rules ( at this time ) and he had lowered the car so that it did not meet the rules of the Class. He told competitors because he was naive about the rules and he fortunately had time to change his Class at the last minute.

Road racing Classes and Time Trial Classes have height rules , so keep this in mind, if it is a concern for the Class you are considering.

What about aero? What about rake? These go with the RH set-up package


So gt350R is running 250/900 divorced springs basically no aero
FP350s is running 650/600@coil like 650/1200 with tested factory aero

Vorschlag mcs kit 600/750@coil like 600/1500
cortex JRi close 650/850@coil like 650/1700

What clues can be gleaned from spring rates?

JRI's 850 spring rate I think is with their rear control arm (0.77MR). So more closer to 1500 @ coil. Either way with basically no aero the lower spring rates are going to allow for more mechanical grip. Personally I'm going 450/750 and JRI had no issues with those rates.
