I already have the Eibach pro springs and Steeda Tower brace, but want to do more to get better handling over 100.

I was thinking of these two upgrades. They seem reasonable in cost and an easy install. Any thoughts from you guys?

Thanks

I personally like the idea of the subframe brace, especially given the problems that some have reported with the IRS wheel hop. As far as high speed stability I'm not sure if it will be explicitly helpful.. The G Trac brace claims to improve cornering stability by strengthening the control arm mounting points but again, I don't see this lending itself towards high speed stability.

I guess my biggest question is does the car feel unstable at 100+ mph? If so, what type symptoms are you concerned with correcting?

I don't feel confident, I had a BMW 128 sport and a Audi A6 Supercharged and I drove over 100 a lot. I don't feel as confident in the mustang. Maybe its the tires..

I wasn't a fan of the stock 18" tires on my car one bit. They were on the car for 200 miles and promptly removed. I switched to 20x10 wheels and 275/35/20 Mickey Thompson Sport Comp tires and haven't had a single complaint. I ran the car at the road course in December with 34 degree temps and reached well into the 130 mph on the very cold straight away and felt 100% confident about it. Even now with frequent blasts to 110-120 mph the car is absolutely stable even at the stock ride height.
 
Their realy is no problem, just that I don't feel as confident as I did with the other cars...Also their is a lot more power and maybe I just have to get used to it.
I have the 19's with 255/45/19 Pirelli Piro Niro A/S tires....I think I'll look into the Bridgestone Potenza. I had them on the BMW and they were an excellent summer tire

I'm starting to get used to the power over 100. I'm going to do a tire upgrade. Question, what track/ road course were you running on?

Thunderbolt Raceway in Millville NJ. They have an open track day one weekend a month that is very reasonable with HPDE instuction
