I understand it'll fit but its totally not necessary and will hinder performance. I understand a spacer can hinder performance too since you could just find a wheel and offset to work without one, but I'd take the spacer at the hub over a 10.5" wheel since all the added weight from a 9.5" to a 10.5" wheel will move the weight out further from the hub which is bad.
On a track car you really don't want to be near flush. You have no idea what certain turns will do with your suspension choices and rubbing and killing a tire is not a good thing. If he wants those wheels I say go for it. They should fit perfect with no spacer at all keeping the weight down. If he wants to track plus go for the "look", then he might end up buying a big rear spacer and a small front spacer.
As for more meat I'm sure he'll do fine with 275's square or even 285's which is the max for a 9.5" wheel. Why you're slipping and you think you need more meat, I'm sure tires could be improved maybe or a better alignment or just ease up on throttle exit.
And yes, rotate FTW. |
Sorry to disagree with you here but lighter does NOT always mean better. If it was simply a matter of lighter is always better, why not run an even skinnier rim? It's simple, because at a certain point there is a trade off. Going too skinny and he loses out on traction. Also considering the weight difference is 1.1lbs per rim plus the added weight of the tire, he's still already shaving a lot of weight from the rims/tires compared to the 19's.
The OP hasn't even mentioned what kind of "tracking" he plans to do. Which would have a big impact on what would be ideal or even allowed. To my knowledge nothing has been stated in this post that 275 was the MAX he was looking for. Only that he was PLANNING on going for that. Going to the 9.5" he does impose the 285 is the MAX the rim can handle though. He also hasn't stated what his goals or future plans for the car are. If he plans on adding more power, the 275 on the rear could easily become a weak link. I brought it up as a "consider your future plans" and upgrade route.
Also considering that his car came stock with 285's on the rear, I see going down to a 275 as a downgrade which is IMHO is a pretty bad way to balance suspension. Why downgrade a portion of your setup to get to neutral or to rotate tires. You should upgrade the part that is lacking, not downgrade the part that has more.
Although, I do not know why I am bothering since reading comprehension is not your strong suit. PharmDZ has stated he is on 10.5 and you seem to have missed that part as well. Others have ran 10.5 square setups and done very very well on the one's I've seen. But then again, you're the ONLY one who knows what you're talking about and anyone who does anything different is an idiot right?
It's racing and cars, there's more than one way to do it. I never suggested my way was the only way, it's merely a hey there are 10.5's that you can go with as well, they fit and others have successfully tracked them.
And yes, as BGTV8 was able to deduce by READING my signature line, I am TT so my needs are drastically different than NA. Which I already stated my needs are different. I'm on Potenza RE-11s, have a custom alignment, Swifts, Nismo struts, dampers etc, Whiteline sways, and adj camber arms, toe bolts, etc. Regardless, my fronts at 285 are my weak link on AutoX. I don't do bad on AutoX, just they are the limiting factor preventing me from going in as fast as I want. So yes, I would like more tire in the front and plan on getting it shortly.
Either way, I took it as the OP was asking for options and OPINIONS. I gave mine and you gave yours. The OP doesn't have to listen to either of us if he doesn't want to.
