Ok this is alittle complicated to explain so stick with me for a second please.


On tire staggers, If you mount

89 3/4in lf 90 rf

87in lr 90 rr

That would give you 1/4 inch in the front and 3 inches in the rear.With your smallest tire on the lr.

OK, to the question if you had a

85 3/4 lf 86 rf

87 lr 90 rr


The stagger would be the same. Does mounting the lf, rf, lr about the same size change the handling because the rr is so much bigger than the other 3 or does it not matter cause the staggers are right on both sets of tires left to right?


To me, it would make the car set-up funny in the corners because of the two left sides and rf being about the same and having one large tire on the rr but, I just want yalls input to see if I'm just over thinking it or not.

I'm not really sure on this either, good question! I'm anxious to see the responses to this. One thing I can think of right off hand is that the differences between the top setup and the bottom setup you have listed is that you'd have to change the ride heights due to that much of a change in the tire size. That way to get it back to where you had it. Probably not much but I figure around a 1/2".

i checked with my car builder about that and he said the front to rear stagger didnt effect the car its left to right stagger. and he said to put bigger tire on rr. Every chassis builder has a different way of setting cars up. I run a imca stock car. anyone else have any input? Modifieds could have a different affect then stock production cars.

If I have your question right the only thing it would effect is your ride height on the left side and you would have to adjust for that...Other than that its AOK

I run 26.5's on the RF, LF, and LR, and then the 27.5 on the RR. I've come to find that the 26.5's seem better across the front, its easier for me to get the front RC right when i got them on. This is with Hoosier's UMP tire.

Were on a Ford clip as well and i think that contributes a little to the front RC problem with the 27.5's across the front.

As well i do believe there is a handling differnce between to 2 sizes. The 26.5 has less side wall and less area to deflect. The tire feels more racey on the track to us.

Thanks guy's, I thought I might be over thinking it, but I didn't want to be alittle off cause it was just common sense.

stagger will help the car turn . my tkinking is the front stagger really dosn't do much except on corner entry when the car
is really loading the right front. the rear on the other hand I feel is way more important . with our skyrocket we have to have 2 inches or it won't turn. getting in the corner you are trying to drag the left rear because the car is rollover so the stagger will help it turn . on the throttle the stagger naturaly makes the car turn . roll a styrofome cup and watch it turn , thats a simple way to see stagger at work. at least the main principle of it.
