Autocross: I got madd questions for you guys!, Info needed for the crowd that autocrosses Options

[jdg371]

Im starting to collect my suspension for an STS Celica. I will be running my Celica in STS[N] for the winter season [3 different series] Being in STS isn't as easy as GSN was.. haha. Right now my stock springs are getting worn [stupid quick]; I will need a replacement as soon as I get the money [haha] For the autoX fellas out there.. what would you recommend???

Some might read this and not get it.. heres an example

Front XX kg
Rear XX kg


--------------------
The only other car I can really base it on are the AE92 Crowd.. although they're lighter [300 I think..] and are more rev happy [Damn their stock 4AGE..] suspension is probably closely related [setup wise]


THANKS!

Honestly for FWD cars, If you increase the spring height in the front and lower the back you get better turning vs lower the front and raise the back. Plus if you run stock tires it actually performs better than aftermarket tuner tires. One plus side if you can't raise the height is to let out some pressure from the back tires and increase the pressure in the front. Adding extra weight to the front actually makes it easier to control cornering when your sliding. Remember your not on an offical track and your just on a parking lot. A parking lot actually slides easier than real roads. What you can do in real life does not count on a lot. So no fancy moves will actually work.........such as hugging a guard rail.

You should never raise the car for autocross. Lower is better. Sometimes you can run less psi in the rear to keep it a little loose. Adding weight to the front isn't a good idea. You get all the weight up there you need when you break, especially in a Celica. I've never seen a FWD car that needed wieght up front. Some could use it in the back to keep them from "flopping" about and loosing the back end though. I don't understand by what you mean by no fancy tricks. You have to hit the best line, and you have to use the cars body role to control it. What other tricks are there? 360s? Not all autocross is on parking lots. And even if I was, different lots have different levels of traction.

i disagree with your logic.

I'm into RC car suspention tuning and this is where i base my suspention knowledge. Since this is a front wheel drive car, it will experience understeer. Decreaseing rear tire pressure will increase contact patch therefore increasing grip. Increase rear grip will make the car understeer even more. I do know inorder to drive a fwd car fast around the track, you can brake hard and shift the weight to the front causings the rear of the car to have less grip. This will essentially cause the rear to slide out allowing you to make tighter turns and decreasing understeer.
