Hi,
I'm thinking about widening the front stance of the car, and thinking of using 1" 3/4 spacers, only at the front, (and maybe 15mm tops at the rear),

Since it's a FWD, I might benefit from this, reducing understeer.... or am I just gonna F up my drivability?



Any Reply would be appreciated!


Oh yes, keep in mind that I like driving not only in straight lines..

 

that's a big spacer...

personally, some people may think it looks goofy, but I would go for a wider rim and tire combo up front. GM did it with their top of the line Bonnivile, using a substantially larger wheel up front to combate understeer. Personally, I think it's a great idea.

As for running such a large spacer up front. Make sure it is hubcentric, as light as it can be.. and you are going to want to think about getting the type that bolts to the hub and then has studs built into it to bolt you rim to. I would not want to have to run 1 1/2 inch longer studs.

Also think of your bearings. the front wheel bearings on the Tib are pretty weak

 

Very good!

Thanks for your reply!
What were the wheels on that car you've mentioned? sizes?





BTW, is it a problem that the wheels are not in one line (front and back) ?

 

sweet, this is what im doing with my car, but 1.50" spacers up front, and about 1.25" in back.

mad machine, wouldnt this setup be better than the extra stud/bolt setup

pressed on hubcentric spacer (pressed onto knurl of ARP studs)
ARP extended studs

i would think the less parts, and room for slop would be a better setup. if its not, would ya like to let me know why its not better?

 

ARP makes some seriously strong studs.. you would probably be able to get away with using them with a simple drilled straight through spacer without worry.

I only bring up the spacers that have the studs pressed into them as they are safer and if done right. you can locktite the bolts into the hub (don't use the super "forever" locktite) and never have to worry about removing them again until it is time to replace your rotors.

This is the way Porsche does their spacers for the "turbo look" 911s.. if that is how Porsche does it, there must be a serious reason for it.

 

hmmm. interesting.. i just woulda thought the whole less parts and less bolts (room for error or minute slop) woulda been looked down upon as opposed to using a spacer thats pressed on with stronger studs..

i may just go that other route now with my spacers (bolt style) and just make sure the tolerances are exact.. might be easier to make also.

 

I was wrong about what Gm car uses the staggered set up.. it is the Grand prix GXP. It uses 18x8 front and 18x7 rear rims with a 255/45/18 front tire and a 255/50/18 rear.. this sets the front up being stiffer and slightly wider (the tire is stretched some on the rim) while the skinnier rim coupled with a slight taller sidewall on the rear makes the arse end of the car "softer" and slightly less prone to follow the front wheels blindly
