Does any one have opinions if the car would under or over steer more if we added a 15mm spacer up front on a 255 square setup?

Thanks.

It sort of reduces the motion ratio so that will effectively soften the front springs a small amount.

Adding 30mm of front track width should reduce lateral weight transfer and offer a little more traction so adding this effect to cracknut's softer front suspension would = more oversteer. The spacers would also add a lot of stress to the front wheel bearings and I think you'd need some major fender work to keep from rubbing the tire's outside edge.

So generally speaking, having a wider front track in an originally square setup would induce more oversteer on corner exit / throttle?

I don't think it'll make an appreciable difference. The wider front track might make it less oversteery as the rear would have to rotate farther around the wider front, but honestly I don't think it'll make more difference than a few psi adjustment in the front tires can't settle.

I'm not sure how that would be effected but "generally speaking" I think wider front track should give a sharper turn in on entry.

I don't understand this.

Any one else have opinions?

iamxpl

question is which are you trying to achieve? there maybe something else you can change to get the result you want? what are the reasons why you would need to run a spacer? brake clearance?

In general, you'll be increasing the scrub radius with the spacers so all the usual things that happen with that will still be at play (a little more steering effort, some increased instability under braking, increased tramlining, etc). I don't think you'll notice any real effects from not using the same offset on the rear.
