True dat. Another reason why these modern rides are so much better

I’m not in total disagreement with J Dog. I love the modern engines, cars, brakes, suspensions. My only point was that he said no old school big block engines (not performance specs) could match up with the Gen 4 Coyote. J. Dog quotes published hp numbers but it is common knowledge that the...

I agree. The Ford Performance School uses wider Michelin Pilot Sport 4s & I had zero spinning or rear end sliding. My DH Pirelli Trofeo R’s & Michelin PS 4 All Seasons stick well. No rear end looseness so far.

I beg to differ. 1. Ford 427 FE solid lifters, 2-4 barrel carbs, 500+ HP - according to Holman & Moody 2. Chevy 427 L88 - 500+ HP 3. Mopar 426 Hemi -500+ (I think) Modern engines are awesome, but old school stuff kicked some ass too. Old school skinny bias ply tires were not conducive to good...

Idk. I drove the DH at the Ford Performance School as hard as I could. Full throttle. Full breaking. No holding back. Back end seemed fine to me. Never broke loose. Lots of turns. No slides. I’m heading back in April for 2 day course & 1 day advanced course. I’ll see how it does then.

The 26.6 & 26.7 are <3% The 27.9 is >3%. I’m hearing stay <3%, but my 2nd set are <3% & I still had problem recur. I’m at a loss for advice except to get as close to stock as possible even if it means getting smaller, narrower tires. And, I’m not sure if the rears matter also.

Hope I don’t sound like a broken record, BUT, Same for me. Ford dealer replaced my CCM (Cruise Control Module) but didn’t fix it. After consulting with Ford big fogs, told me it was the taller front tires changing the angle that the windshield camera had with the road, affecting the data inputs...

I calculated it in past. Don’t remember exactly but it was outside 3%. Put stock 19s back on. Had it recalibrated. Then put smaller fronts on that are within 3% & problem recurred. Front : Pirelli 305/30/19 stock; tried Michelin PS AS 285/35/20 then 285/30/20 (only 0.4” taller than stock) if my...

Beware. Your summer setup may cause you to lose Pre-collision Assist & cruise control functions. It did with me. I would recommend trying to stay with stock size wheels (19s) & just get tires that are similar diameter to your stock tires. These computer troubles are killing me.

Regarding squared setup and tire rotation: the offsets on the wheels are different in front & back. Mine are +24mm front & +50mm rear. How can they be rotated? I don’t think they can be moved around. I could be wrong. Open to education.

It’s not just the wheel diameter. It’s the wheel & tire overall diameter that affects revolution/mile that the computer monitors. You can have a taller wheel and get a shorter, the same, or taller overall diameter based on which tire you put on it.

I like the design & the idea. Not sure about the colors. Brown & tan look out of place. But overall I still like it.

I can’t answer your specific questions, but, I think the price of the Ford unit is similar to the aftermarket ones. And, you can call them & they will confirm that it fits your car. When I purchased mine from Automotive Authority, they asked if I had a Dark Horse, implying that there might be a...

I had 285/35/20 fronts like you. Pre-collision assist & Cruise went out. Got it back with stock setup. Come cold weather, put 285/30/20’s on (26.6” diameter stock, 26.8” diameter for 20’s). Worked fine for a month, then problem recurred. 305/35/20 rears. I’m confused. I seem to be the only...

Are you having any problems with Pre-collision assist & cruise control since you changed to 20” rims & those tire sizes?

What size are your front and rear tire sizes?

I have not, yet. I’ve been thinking about it but just too intimidated about changing factory settings. I would need some help from someone with more tech experience than me. Dealer said the Whipple software lets you change tire size too. Thinking about going that route. Anyone near DE with...

PS. I’ve driven the DH at the Ford Racing School & the C8 Stingray & the C8 Z06 at the Ron Fellows Corvette School. Drove both as hard as I could. No holds barred. The DH is no slouch. It took all I could give it in stride.

My pre-collision assist is out along with my adaptive & normal cruise control. It has been attributed to 20” wheels & larger diameter tires. Resolved when I went back to stock setup. Put 20’s back on in the Fall with different fronts closer to stock diameter. Problem back. Haven’t had it...
