For road racing or autocross: do suspension mods make much of a difference?

I know they make a difference, but is the difference significant enough to be worth the money?

Does anyone have any lap times to post before and after a suspension upgrade?

I'm looking at something like the Ford Racing kit with shocks, springs, sway bars.

Yes! Suspension mods make a tremendous difference.
The tires are where the big gains are made though...

+1^ I don't have lap times unfortunately, but a spring upgrade on my car helped reduce nose dive and made it a but tighter in the turns. Then I swapped to an IRS and set my alignment specs to give me a bit more toe out and that helped greatly with turn in and steering response in a turn. I haven't made a trip out since my latest batch of upgrades though

This is also my daily driver, so putting track tires on the car is not practical. But, "tremendous difference" is what I was hoping for!!

Summer tires make a pretty big difference compared to running the stock all seasons. I have to push it pretty hard to make money break loose

That's the kind of package I'm looking for. (And I wish I could get on to the Gainesville Raceway road course. LOL)

As stated, the tires are going to make the biggest difference. Simply swapping from the all weather to summer series will be a huge change. The biggest handling issue that I had with the stock mustang GT suspension was with body roll, dive, and the horrible tendency to understeer.
This can largely be fixed with a good set of shocks. I swapped Koni Yellows into mine, took it out to an improvised skid pad and dialed it in on the new tires. Makes a WORLD of difference.
I was envisioning having to change the front or rear sway bar but I am holding off for now.
The overall characteristics are very well balanced now and I am leaving it alone.

For the record, these changes can be made while remaining in F-Stock SCCA class.

I'm trying to keep the car daily-driverable, so I'm avoiding summer tires. But, the body roll, dive, and understeer is really annoying since my last car was a Genesis Coupe so I got spoiled by the incredible handling.

So you changed the shocks but kept the stock springs?

What year and model is your car? That will help figure out what is best for your car.

That is correct.

The stock spring rates are actually not bad. The problem is that the stock shocks are way too soft. Great for road trips and that Cadillac feel, not so great for autocross or road racing type applications. The Koni Yellows on the softest setting are much more positive and help a TON.
I run them like that for daily driving and they are just fine. At the track I have settings that are a lot harder. It is possible to go too hard though and the spring will not be able to return to its neutral position fast enough if you tighten these down too much. The trick is finding that line or going to different rate springs.

Suspension
If on a "budget", although all suspension set-ups are very expensive.
For me- I want a superb handling car for safety and spirited driving. Basically, I just lowered the cars I have. I believe that I have done it the right way. I have a SN95, a '97 coupe & a '96 Cobra.
I just lowered them both, thats all. Parts list:
springs, shocks/struts, caster camber plates, X2 balljoints, bumpsteer kit.
Thats the most simple suspension upgrade to do but the results are unbelievable.
Good Luck! Enjoy.

I don't know where you live, but in most places, summer tires DO NOT deter from the driveability of the car at all, in fact, they enhance it.
Sure they may be a little noisy and wear out faster than you're used to, BUT, the tires are everything.
Shocks are important as well, although, I've seen some smokin' fast Coyote powered cars in F-stock, that were all stock except for 200 treadwear summer tires! Those cars, well driven, are routinely faster than the modified New Edges that dominate ESP. Hell, I've seen Coyotes in F-stock that were faster than Coyotes in ESP!!!
You'll get used to the Mustang handling... you just have to keep the front end down .

I've had summer tires before. I'd rather spend my money on durable mods first.

Your car will feel completely different with those items.
