View Full Version : Autocross anyone?
04-19-2012, 11:38 PM
Well now that I have enough power to get my tank moving, I'm looking into trying to keep it planted to the ground in turns. I'd love to be able to partake in some of the autocross events around here and surprise some of the little cars out there. I'm sitting 2/4 right now, and that's about all I have in the suspension. What all do ya'll think I'm looking at to keep this thing rolling smooth? New sway bars are the first thing on the list, but after that what other options do I have to add even more stability?

Lots of good ideas in the pro-touring section at the top of the street forum. Sway bars, poly bushings, sticky tires, and a sport steering box are all nice upgrades. All things in my near future as well.

I've heard about poly bushings being a good upgrade but what difference does it really make?

Predictability. It keeps everything where it belongs. They don't flex therefore changing your geometry. I can make a big difference especially if any of your bushings are getting at all worn.

Ah, I'm looking at a HUGE difference then, once of my sway bar bushing it slipping out of place...

Reduces steering deflection where rubber tends to flex , poly doesn't which in return gives a more solid feel in the steering

It is well worth if from what I understand. Especialy if you have any bushing that are showing signs of wear. You biggest differance will come from getting rid of those joke ass tires(as long as you still have the ones in your sig). A lambo would handle like **** on those wheels and tires. Get a nice set of 17 with the lowest profile tire possible and it still look good, that will make a MASSIVE differance. I am sure going lower will still help some since you have such a mild drop. You will **** your self when you get some really rubber on the road that doesn't have a 10" sidwall flexing all to hell.
The next extream step would be 4 link and bag or coil over the rear.

Wheels and tires are definitely high on the list probably the second most expensive thing I have left to do on the truck. I'm going to convert to 6 and run some SS replica 20's, so I'm just half assedly searching for a rear end while I deal with the rest of the suspension.

Till you get wheels and tires it will never handle worth a crap. Just plain and simple. It may do better then it does now but it will still have the handling of a fart in a wind storm.

Well I guess that should be the first thing on the list and just go from there.

Defiantly. Same concept of rubber vs poly. But much more extrema! Not only do those tires not put much rubber on the road that massive sidewall flexes and sways. When that happens it distorts the contact patch and doesn't give you any feel of what could actually be going on. Is the tire flexing or is the truck sliding? There is a trade off of wheel size and weight so that is why I said something in the 17" range. You could go bigger just do your best to keep an eye out for the lightest wheels possible.
As far as tires you don't need a tiny rubber band but you do want as short of a sidewall as possible. 245/55r17 is 28" tall so is 245/50r18. Those should be close to your stock size and hopefully fill most of the wheel well.
P.S. Are you ever going to paint your bumper to match? That drives me crazy looking at your sig, the bumper sticks out like swollen sore thumb.

Thanks for the help! And I already have, it matched before. Just the angle of the hood and the side of the truck makes it look a difference color.
