    Best tires and rim size for racing

    Shouldn't be too long. Another member has an ST without a sunroof on JRZ RS 3 Pro coilovers that would be perfect for this kind of driving. The absolute best setup for grip and cornering performance.

    Review: Steeda front and rear sway bars, Steeda tower brace and Eibach lowering springs installed

    That's great info, thanks. Would running a stiffer front sway bar benefit an explorer with air suspension on sticky tires? I have a lot of nose dive and body roll during the initial turn-in on a hard corner and would like to lower that as much as possible while keeping the air suspension...

    Thermal R&D 3” exhaust

    Meant to say it's cheaper to install them altogether than the exhaust now and downpipes later. Late night text lol

    Thermal R&D 3” exhaust

    Downpipes will help, might as well get them both to reduce overall labor cost. https://youtube.com/shorts/oxvH7QN6M4Y?si=WOBw099Twn0qEKE4

    Best tires and rim size for racing

    Sounds about right. I will look into it closer to the completion date. The brakes are great but the air suspension will never outperform coils; hoping we can tune it to perform better without overstressing the bags. If we can get them to be at a high PSI while lowered, it should reduce the...

    Cold air intakes 25 ST

    Wouldn't surprise me if they wanted to make sure the warranties expire before letting people tune these after all the diff bolt failures they had to replace. Saving pennies ended up costing them a lot dollars.

    Best tires and rim size for racing

    Ideally both. I'm being told I'm getting ahead of myself and should focus on suspension before tires though. I don't mind it being slow for a track car, but want to handle reasonably well and increase the G-force by 0.1-0.2 on a skidpad test without switching from the air suspension to...

    Best tires and rim size for racing

    It has two Xona 5451S turbos. The plan is to downsize to 4951S. Not trying to ever run a tune higher than 825whp | 825lb/ft until someone else pushes the engine further and finds the limit though so I was hoping to get the flattest power curve that could make 800whp reliably...

    MBRP Axleback or MRT H-Pipe and Tips?

    Custom X-pipe exhausts sound beautiful on the ST. Worth asking how much that would run you if you know a good shop. https://www.instagram.com/reel/C7Ff_TiRSAS/?igsh=MXJwNGl5Y21pbm16MQ== https://www.instagram.com/reel/C7abopVMvmN/?igsh=eTdnaXVqNGp6b2I4

    Down sizing from stock 21" wheel to 20"

    If you are planning to put the Shelby GT350 brakes on, I would go an extra 5mm on the offset. A member with 20x10.5 wheels on a +35mm offset had to use a 10mm spacer to make them fit. 30mm would most likely clear those brakes but the 25mm creates an ever-so-slightly more aggressive look.

    Shot a promo for Houston Speed Freaks of the Under Tray

    It will improve aerodynamics and protect the bottom from corrosion which is a major concern in the Midwest. HSF just released a carbon fiber version today that's on sale for $1,400. HSF together with ZFG, Fenfab and RSA have done so much for the platform that I would never argue about price...

    Best tires and rim size for racing

    They redesigned the front control arms to be slimmer so I'm hoping that would solve any issues. We really need to see a review of their updated version to know for sure. I really don't like to see people having issues with earlier versions of their parts, but if it can happen to Steeda, it can...

    Best tires and rim size for racing

    Agreed. Seeing the aftermath of Explorer wrecks is very confidence inspiring, these things are tanks. Pretty much have everything covered except control arms and confidence-inspiring coilovers. I had front end-links replaced about 300 miles ago with the Steeda's and will be looking checking to...

    SLD 21" Stock Rims Free to a Good Home (Atlanta Metro)

    Labels sent, please let me know if there is any other way I can help. My main shipping service got shut down out of the blue and I had to scramble to create an account with another company.

    Best tires and rim size for racing

    100% agree with all of your points. I'm not trying to be the first one to hit 200mph unless there's a tempting financial incentive. All the data points to it being a reasonable expectation with all the new parts. I just want to make sure I'm overbuilding it for my goal which is a reliable...

    Best tires and rim size for racing

    Definitely agree with the aerodynamics being suboptimal. One thing I have to point out is that the coefficient of drag is surprisingly low on the ST (0.35) The following cars have worse aerodynamics than the Explorer ST and are getting very close to 200mph. Lamborghini Urus SE c/d 0.39 (top...

    Best tires and rim size for racing

    That's were things get interesting. I hit 170mph on a 93 tune with the stock block and it took about 5 seconds to go from 165mph to 170mph. But, doing that without a total suspension overhaul was a terrible idea in retrospect, more on that... ZFG is building blocks that have forged rods...
