    2001 GT "Old Car Jostle"

    Tires make a big difference. Get some new rubber and it should feel like last season. :nice:

    2001 GT "Old Car Jostle"

    The factory setup does many things to reduce noise/vibration/harshness. Changing tires, bushings, and springs all will change how it feels. I’d start simple - the springs and shocks/struts are what changed. When you installed your springs - hope you put in spring isolators...

    budget blower for v6

    With a v6 I’d go turbo. Has the most potential. There are very few / no kits. Be ready to have to custom built setup. Considerations: 1) find a good tuner / good mustang shop to help you 2) find a good welder for a custom exhasut manifold and custom piping. 3) Single 61mm turbo is a...

    All season or Summer? 35 or 40?

    I remember having all seasons with just boltons. Little squirrelly at temps that low depending if I was slightly too spirited in my driving (when I lived further north). With that weather - If it were me I would keep the old rims and put winter tires on them to insure the best possible...

    New thottle body or no

    75mm TB is good for a couple horses. If your plan is full boltons there is no need to wait for headers to get some small gains now.

    All season or Summer? 35 or 40?

    What do you have now for wheels and tires? 255/35/18 front and 285/35/18 rear would look great. When picking between summer and all season tires make sure you look at your weather & power levels. As an example I live in the South so I never worry about snow or freezing weather. I use summer...

    Advice on 03 gt build

    The stock motor is generally good to 400rwhp with a power adder (nitrous/supercharger/turbo charger). If you are new to performance upgrades I wouldn’t dig in the motor first. I would first do all the basic maintenance (ex: change out brake, transmission, engine oil, and rear end fluids) and...

    Wheel Combo questions/suspension

    Nitto gives a range of wheel widths. Half way down this page is a good explanation of the ranges that will fit and how the tire width will change: https://www.tirerack.com/tires/tiretech/techpage.jsp?techid=194 I’d trust the manufacturer’s range of 9.5-11”. The 285 will fit on a 10.5” rim...

    Wheel Combo questions/suspension

    Supercharger adds weight but not much. My car with full interior weighs 3,300 lbs - with just boltons it weighed 3,240lbs (most of that was supercharger plus intercooler - probably not all). If you were to have a similar weight difference with normal aftermarket springs you are talking about...

    Wheel Combo questions/suspension

    Those springs should give you a good stance. It is worth it to pick high quality shocks / struts like bilsteins or MM’s in house brand. I would install a bumpsteer kit and CC plates - helps make alignment easy with a lowered car. Set camber to neg 0.5 deg, caster to positive 4.5 deg, and toe...

    Wheel Combo questions/suspension

    Nitto under their sizes and specs section has recommended wheel widths for each tire size. It gives you the tire heights and tire widths when the tire is inflated...

    SN95 stock sway bars adjustable??

    The stock sway bars aren’t adjustable. If you are a road racer / track fanatic and need to tweak your suspension to get that edge - that is who the adjustables are for: https://www.maximummotorsports.com/Adjustable-Rear-Swaybar-solid-axle-Mustang-1979-2004-P546.aspx For the vast majority of...

    Question about 04 GT + vortech

    With that size pulley I’m making 4 psi at 4K rpm and making 9 psi at 6k rpm+. At idle and with normal sub 2k rpm driving I see nothing on the boost gauge - that’s normal. Does the seat in the pants feel like the supercharger is producing boost? Take pictures of your supercharger setup and...

    Front suspension part names (for 2000 GT)

    Steering rack movement is never desired. The bearing on the inner tie rod is the part that needs to move - not the rack. As long as you have properly functioning inner tie rods you have no increase in NVH. :nice: The solid steering rack bushings are the only solid bushing I would recommend...

    Front suspension part names (for 2000 GT)

    The other parts are labelled correctly. Sounds like some steering system issues. That is where I would focus your efforts - Tie rods wear out. Worn struts don’t really make those symptoms. Worn ball joints / arm bushings can make more groaning noises but not the strange steering symptoms...

    Front suspension part names (for 2000 GT)

    That is a ton of stuff to replace all at once. Are you having a problem with the car triggering this? The first photo is a steering rack bushing. I doubt that all of those things need replacement right now - don’t totally rule out aftermarket parts (most are much better than stock) and find...

    Need Advice on Rear End Gears

    Probably cheaper to drop one pulley size and see if that is the pep you were looking for. Stock block can take a pulley size drop. If that is not enough pep than look at your long term goals and determine what gear lines up best with the 1/4 mile trap speed you are looking for at the top of...

    Seeking Guidance - Mild 2V build

    If you call them you can customize your setup. I’d get their biggest throttle body and get their big air intake as well. They send a tune with their kits so you can discuss what injectors are best for which setup (and with future goals in mind).

    2003 GT 4.6 - Best exhaust from 3 options

    Flowmasters sound great on our cars. You’ll “learn” how to drive it to get the sound you want. Enjoy your new mufflers!

    2003 GT 4.6 - Best exhaust from 3 options

    Exhaust comes down to user preference. 1. I had Weld in mufflers previously - cheap way to change the sound but I found that cat backs are much higher quality. I wish I would of done it right the first time. My borla catback looks fantastic now nearly 10 years later. 2) I found that my...
