I ordered a set of 5zigen pro racer GN+ in bronze for my car from edgeracing.com, and when I ordered it it was initally 18 x 7.5 with a +48 offset... however it seems like they shipped out the +43 offset instead (according to 5zigen, both offsets would "fit") question is, am I gonna encounter any problems such as rubbing? or perhaps I cant lower my car as much? I am assuming the +43 will sit more flush with the fenders and I have more clearance if I do plan on doing a brake upgrade in the future.. but for now, can anyone tell me that the +43 offset wont be too much of a problem? (running 225-40-18 tires) Thanks in advance!

 

no problems with rubbing.

 

Yeah, you should have no problem. I'm running 225/40/18 w/ a +44 offset.

 

you will be fine. I am running a 19x8 with a +45 with a 225/35/19 and I have no rubbing up front at all.

 

You're fine. On a 7.5" wheel and a 225 wide tire, you'll not have much trouble.

 

thanks alot everyone for the prompt responses... pictures coming this weekend.. =)

 

Such a big change from existing offset may not cause rubbing on the TSX,but it will change the fundamental steering geometry to your vehicle.This can cause premature wear on tyres,and if youre a hard driver,premature wear to wheel bearings and such.This happens because most cars are set up to run zero scrub radius,ie the angle formed by the line through the ball joints and the perpendicular line through the centre of the wheel should meet at, or on, the road surface.When you change that angle inwards or outwards by decreasing or increasing the wheel offset(from factory setting,55 in the TSX case),the meeting point of those lines is either above or below the road surface.When that happens steering can become lighter or heavier,you can get tramtracking,and you can get a loss of self centering after cornering.
I'm always puzzled how enthusiasts will spend so much money and time buying performance equipment and setting up their cars so precisely,then throw it all away when it comes to choosing rims.Mind you the choices out here in Australia are bloody woeful,so its no wonder most guys just say to hell with it and buy what they can.As it happens thats just the position i'm in right now.Stick to your guns IMO,get the 48ET rims,at least they are closer to stock,and drivers over here are saying that steering changes seem to be minimal at or above 48.

 

If he really plans on doing a brake upgrade that +43 might be the difference between clearing and not clearing a BBK.

 

Yea,thats true,guess it depends on your priorities.For me, steering setup is all important.The TSX has a very responsive and crisp steering setup, the idea of changing that"feel"to me is like changing the whole character of the car.But if outright performance is what people want then i guess they will do what they have to do.
I think the brake clearance issue will also depend on the spoke design of the rims.Its really a "fit it and see"situation,and hes not going to know until he fits up the caliphers and bolts on a wheel.Im out of the loop mostly now,but are suitable aftermarket caliphers much bigger than those huge fugly things on there already?

 

Size difference, yeah, sadly, the only ones close to stock size are the Spoon ones.

 

I could not have said it better myself.

 

Advan by Yokohama make lightweight racing wheels that work on the TSX.Look great too.The models and offsets available are...
Advan RS in a 48ET
Advan Connoisseur 151C in a 48ET and a 50ET
Advan Kreuzer Series X in a 45ET and a 50ET
They have some other models as well in the more traditional 5 spoke designs,some that look like RonJons

 

where the pics at?

 

I'll see if i can find the pics for you,in the meantime have a look at the 118 pages of new and S/H wheels those lucky bastards in the land of the rising sun can choose from.

OK, found the link easier than i thought.This is a local Aus shop that brings in these rims from Japan(for a price).Im sure somebody over where you are most likely imports them as well.Some of these designs really suit the Euro/TSX.
