suspension info

Hey guys. i recently purchased a 91 si hatch, its has head work, 7lb flywheel, header and some other small mods. I am lookin for some infromation/products to make this thing ride on rails. Any tips would help out alot. thanks.

stiff sway bars, wide wheels, and stiff, lowered spring. it involves way more than that, like perfomance shocks, to handle the lowering, camber kits to help keep suspension geometry, and maybe some chassis strengthening.

Good set of springs and shocks. Watch upgrading to a bigger front and rear sway bar...a rear sway bar will help, but don't go too big on it.

Camber kit shouldn't be needed unless you are sitting the damn thing on the ground, just after you lower it go get it aligned and get the Toe set correctly. Camber isn't the main cause of tire wear, its Toe.

One setup works great for one person, but might not be great for some one else. You will just have to experiment some and find out what you like and want. Do a little research to find a decent starting point and go from there.

You cant just go throwing big sway bars and off the shelf springs on to get your car on rails, it takes more thought than that. You need to look at motion ratios and spring frequencies etc. Luckily I found this awhile ago.

Thanks guys. I should have started by saying i want to auto cross the car and it will be mostly a track car with plates on it. The other thing is it does have a cheap set fo coil overs on it as well as camber kits and the rear bushings have been changed to poly. What i don't want to do is throw money out the window on parts that work half assed. I do know alot about cars just not alot about name brand stuff, and combinations. i was kinda thinkin koni yellows and a set of springs, and brace the hell out of it and change all the bushings. i will be running a set of 15"victor 700 for rubber.

Tires are another consideration when looking for your "perfect" setup... lower profiles aren't always better. I know guys that have run 175/50R13's and pulled better times than guys on super sticky 205/40R16's. Again, it depends on preference and driving style.

also look on Honda-Tech...just don't make a thread about it

Look for adjustability on shocks, coilover sleeves or complete coilover setups. If you have the cash to spend, a complete coilover setup would be nice...I don't know the difference between the brands because I haven't looked into them really.

Koni Yellows are a great shock from what everyone has told me. Excellent adjustability out of them and easy to send back and get customized to your likings as well.

Ground Control and Skunk2 make good coilover sleeves if you want to keep the adjustability. From my understanding the sleeve is the main thing that seperates the cheap kits from the more expensive kits. Ofcourse the spring comes into play, but you may end up swapping that out anyways for a stiffer/softer spring for your likings.

Tires also come into play like Dropzone mentioned. Talk to some guys that have raced auto-x, see what their driving style is if you can and see what their opinions on tires are.

Frodo will probably give better advice than me, because he actually has raced autox..I have only went around in circles.

Tire choices are pretty much the falken azenis rt-615, the hankook rs2 z212 (my choice), and the new dunlop direzza (friend of mine just got them).
