Best Mods for Autocrossing ??

Iroc Killer · May 10, 2004

I Autocrossed my 90 Stang this past weekend. I got spanked by a 97 Porche convertible. My car is Stock except for pulleys, hollowed out cats, Flowmasters. I have the 15" turbine GT wheels w/ 225-60 Fuldas.

What mods should I do first, and for the best time gain. I don't need and power increase as the Stang is faster than the Minis, MGs and triumphs already.

I was thinking of getting 17x8 Bullit wheels with 245-45 Nittos to start. Then replace the rubber bushings with poly. Then 1" lower springs.

Sound OK? Suggestions?

here's good start for auto crossing from cheapest to the most expensive
1. polyurethene bushings through out the car
2. Stiffen up that chassis, sub-frames, strut tower brace, g-load brace
you would be very suprised just what these would do in your times
3.eibach progrssive rate springs
4. gears 3.73
5. good tires
6. koni red's 3 way adjustable shocks and struts tolerable on the street, koni yellow's are better but ride quality sucks on the street "they rattle you teeth"
7. 4 wheel disk brakes a good kit 13 inch rotors,dual piston calipers, when you start with the above your track times will greatly improve which means your going faster and brake fade need's to be addressed autcrossing is like drag racing it get's expensive fast. Hope this helps you out

torque arm and panhard bar

I also plan on doing some autocrossing. I pretty much did the stiffening of the car. I plan on putting the panhard bar and torque arm on this weekend! Check out the suspension page in my link. Theres a breif descriptiong of the stuff I have and what it does. This is copied from the MaximumMotorsports website itself.

roll bar and subframe connectors help as well as well as everything else QwikSVO said.

What brand tq arm and phb you have? Is it all the hype it claims to be when it comes to traction?

some good brake pads... mine suck u try to some quick from 70+ they either lock or if u pump them they evenually get too hot and give out... but i am cheap and just keep replacing them with autozone life time warrenties cause it is free.. it is just about every 8k i have to replace them...lol

I'd check out the SCCA rules before you go modding your car so you will be prepared when you get classed. I'd also see if you could attend a driving school b/c the best mod you can do is THE DRIVER! The next best mod is a set of sticky race tires. The best mods I've done (besides the 2 mentioned) are: Maximum Motorsports starter kit, panhard rod and a Torsen T2R differential (fried out my Trac-lock at 1st event).

Michael Yount · May 10, 2004

I'm with BnGRacing - the two most important first things (assuming the car is in safe working order as far as brakes, suspension, etc.) are your tire choice, and tightening the nut behind the wheel - go to driver's school. DO NOT mod the car until you've been to school. As your skills improve, your mod choices will change. You will become a much better driver more quickly if you learn how to go faster in the nearly stock car, than if you mod the car to go faster.

not east to beat a autocross porche with a stock fox body gt.................................a full M&M suspension will be better than that of a porche.

Maximum Motorsports. I have the Heavy Duty Torque Arm. It's badass. I could really use some Konis or Bilsteins to really make it corner nice, but it's awesome none-the-less. Need to get my CC plates on too. They don't do any good collecting dust in my room, lol.

there's some more cabin noise because of the torque arm, but it's worth it to me.

What's a porche?

I think it's a plant.

Michael Yount · May 11, 2004

You might be a redneck if more than 3 dogs are killed when the front "porche" collapses under the weight of all the rockin' chairs.

It’s like a porcupine, except all of the pricks are on the inside.

Michael Yount · Sep 3, 2004

Sinewave - I believe you're confusing a porche with a Porsche. And careful; your jealousy is showing through.

QDRHRSE · Sep 3, 2004

I agree with the fellas about the rules- check them out first and then decide what class you want to race. That way you will know exactly what you can and can't do and also what you should and shouldn't buy.

5.0's in stock form aren't the handling cars ever built. Anything will make one handle better. I think that you should start with sub frame connectors, bushings, shocks/struts, and camber/caster plates. You can do wheels and tires any time as they just require a quick bolt on. Then once you get things rolling I would do springs,panhard bar, and maybe a torque arm.

GTPhreak · Sep 3, 2004

the best mod is learning to drive your fastest...just keep going out and get a good feel of it before you start modding your car

Michael Yount · Sep 3, 2004

Yup - tighten the nut behind the wheel first....
