Those of you that are running square ... do you need to do anything special in the front i.e. spacers, roll the fender, etc. to make things fit?

 

Nope

Camber which is what u want anyway

 

I rolled my fender as the tire can get close to it and I didn't want have any issues.

 

Mine rubbed a groove in the spring without spacers.

 

roll the fender and you need a wheel spacer

 

False

 

I went from staggered to square. With the larger fronts, I heard a rubbing sound when the steering was turned all the way to lock, that wasn't there before. There's very little space between the tire and the spring even when the wheels are straight forward.

So I added a 2mm spacer, and the sound went away.

I have no rubbing against the wheel well.

If you don't turn your steering all the way to lock, maybe you don't need the spacers. I know a number of racers here in norcal who have spacers but don't use them. They trailer their cars to the track though. Mine is street-legal and I drive it to the track for DE days, so I need to be able to turn my steering all the way--for parking and so on.

 

3mm spacer.

 

No spacer on mine, never noticed any rubbing...

 

*One of the stock rear wheels legal for the class? Will require a spacer in the front. The standard issue "twist" wheel will not need one **unless you are on some oddball springs besides a Swift or Eibach.

If you hear rubbing? It's the tire touching the fender liner. Notch the factory radiator brackets and move them forward .75 of an inch. The fender liner attaches to the bracket and will move forward with it.

Lots of people roll the fender lips.. but unless you are super low in the front? It's not needed. And as a side note? If you are *that low? You should probably check around and visually measure the top 3 SPB's at your next event

 

Rolled fender on mine and run with and without spacers just fine.

 

Is there generally perceived to be an advantage to the square over staggered setup?

 

I've gone both ways. Square gives you more grip for turn-in but especially on longer tracks; the additional unsprung mass and rolling friction might off set the advantage. So the answer is: Maybe.

 

I have run the offset at ctmp and mid ohio, thinking the offset provided less rolling resistance in the front equaling more straight line speed. I have not run the car square yet.

 

What size tire are u running square? 255?
