I'm glad you started this thread, OP. I've asked some questions in other threads related handling and things on the topic but really didn't get too much help. As OP noted like 75% (or more) of threads are about who cut what 60' time or what Drag radials to use, etc., etc.
I started my build trying to get close to being a GT500. From what I had read over on the Forum they handled rather nicely and with a few upgrades, they were pretty good. I digress...After being dicked over by a dealer on a GT500, I decided to go the 5.0 route and build my own car with my 'thumb print' on it (backstory over!).
In any event, my build started with more of a straight line focus but I knew I needed to change a few things for the car to really handle well. Realizing my current 'go fast' mods aren't ideal for the track, I am looking for a little more to upgrade the suspension for the track, while still keeping manners for the street. One suggestion i did get was that I have too much rear tire. I get a bit of a push in turns. So i need more front tire or less rear. Also my adjustable sway bars may need some tweaking. I think my next upgrade will be Koni's (yellow) other than that, i'm not sure what else to do. See sig for mods. Any thoughts are welcome?
The only real power mods I've done are a tune and cat deletes. Honestly, the power that comes stock is already so much. How many people can really lay out all 400 whp through a live axle coming out of a corner?
you don't need less rear tire just more front. maybe you could go down 1 size in the rear and do something like 305 rear 285 front. mainly though you need more front tire, 255 is way too skinny for your 315's. if you simply put 285's up front on a 9.5" rim and stiffened your rear sway bar that understeer should reduce by a lot. Kenny brown runs 18"x10" front wheels with 295 section mpss's and 18"x11" rear wheels with 315's on the gt4-s. Im not sure about fitment of 10" wide wheels up front though, not sure if 19"s would work that wide. I personally wouldn't want to go down to 18's.
I run 285/35 square and it feels balanced as hell - as long as you have the suspension out back to really take advantage of the tires. Wide as hell tires don't get to do a lot of work when they are bouncing around.
square setup works great but when you start putting down over 450whp staggered starts to become ideal for corner exit. but remember with any suspension setup alignment and tuning is key you cant just slap parts on and expect it to be perfect... you have to test, tune, test, tune... repeat until it's just right. nothing like destroying a 911 on the track with a gt mustang.

Staggered setups are conducive to understeer. Squared is the way to go IF possible. I've run 315/30-18 Hoosiers on 18x11 f14's on ALL 4 corners. Best set up I've ever experienced on a mustang.
11" wide in the front!! damn i thought 10" was the max we could fit up there.
with stock wheels and tires (brembo wheels + Pirelli p zero 255/40/19's) all around my car begins to slide around as you give it power on corner exit... as im not too experienced just yet i'd rather set my car up for more towards understeer than. besides the balance can always be altered with suspension tuning as well. plus staggered life bro
so guys im about to buy a whole new set of shocks struts and springs. right now its either gonna be the frpp adjustable's with k springs or the Kenny brown spec eibachs.
the Kenny browns are only adjustable for height as the frpp's are only dampening adjustable. what do you guys think? either way im gonna also go for a bmr uca and lca's. adjustable panhard for now, wattslink and sway bars will come in the future.
Beefier sways make the car feel more responsive and of course basically eliminate any body roll
