Answered. I have -2.2 camber all around. Haven't driven the car enough to comment on the really fast wear beyond -2. My budget is tiny, so I hope you are wrong lol :uhh:

im thinking of going to a -2 because my rear tire is rubbing when there 4 people in the car or when im driving by myself and i hit a dip in the highway or when i take a quick turn. I mainly drive my rx8 in the weekend put maybe about 300 miles per weekend. Im already looking into the option of getting tokico d-specs and tein s-tech to make the right a little stiffer so it doesnt roll/bounce as much. And i do have my rear fenders rolled. It seems the place where it rubbing the the piece that connect the bumper to the fender.

There seems to be so much info out there that I'm caught up in a whirlwind looking for what I want.

Basically I plan on running 245's all around on 18" rims. I plan on using some deep dish rims so an offset of anywhere around 30-40 likely. Front and rear tires I want flush with one another as well as with the fender as far as they can go out, perhaps even slightly pass the edge of the fenders.

18x8 or 18x8.5 seems to be the ideal selection. Anyone propose wider? I don't want the ridiculous stretched tire look which IMO looks ick. I plan on dropping the car some more from stock but not slamming it which also IMO on a sports car looks, ick. Low is good, but there's a fine line IMO what looks good and what is too much past good taste.

Mainly the wheel width and offset will dictate how far out the tire goes and if the fenders need rolling or not depending on the drop. Does anyone have pictures of this set up with a drop showing the tires flush with one another and the fenders that didn't require a roll? Or do they absolutely need a roll to get the tires flush with the fender?

Is it a black plastic piece?

Vlaze: Look into an 18x9 +30 (jantzenrx8 or wvboosted) or 18x8.5 +25 (dezau or dozer). If you want to be a little less aggressive, add 5 to the offsets.

It is a plastic piece but i cut that off but now under that you get a lip that holds the bumper with the top body frame. It has a screw holding bot pieces together some im hesitant of cutting it off. I was told by a local guy that i could do that or get more of a negative camber.

You shouldn't be rubbing on that. 18x8.5 +30 with 255/40? Aren't your shocks messed up? https://www.rx8club.com/rx-8-multimedia-photo-gallery-6/p45fs-dozers-vr-173209/ 8.5 +25 in the rear without rubbing but he has 245s so it is effectively the same setup.

Yeah but just throwing ideas out there to see if camber would help the situation.

For some reason Vlaze thinks that anything wider than 245's are way to big for our car...

Not sure where he got that idea...

I do think from my perspective, that anything larger than that on a solely street used car for the power we make with an NA engine is overkill. That's just my opinion.

Again like the style everyone else uses, they have their own reasons and preferences, those are mine. Maybe in time I'll change my opinion but for now for what I use the car for with the power available I don't see a need to go bigger.

Maybe for drag racing N/A? We don't need tire for the power we put down, but we can use tire in the corners.

Camber can fix just about anything lol. jk. Yes it will help the situation, but you will be making your wheels look less flush + burn through tires faster + not be fixing the real problem (shocks).

Ok well for a street driven RX8 then yes 245's are a great choice. My mind is always on what tire is best for track use, which is why I made that statement.

I completely agree with you J8. But again, for a street based car where I'm at not having a chance to just go WOT all over the place, it's no benefit to me. If I used the car for tracking as well then yes I could go bigger but for my application it's not needed and thus overkill.

Ill be placing my order for the tokico d-specs with my shocks by this friday.

I only drive on the street, but I do look for every opportunity to find a great corner. I've overcome my 245s on the street lol.

Shijin-Kun: Good luck on the install. Get some better pictures of your wheels!

^ ill try

When I had my car aligned and corner balanced one of the first questions they asked was how many miles did I want to get out of the tires :lol: Too much toe and camber and you will burn though tires very fast.

Yea the people who track say to 0 the toe out if you have to run camber.

I think that depends the type of cornering you are doing at the track :)

Or it depends even more so on how long you wish your tires to last :)

*sigh. . .

My quest for wheels continues... thanks for imput and others for addressing my questions in here when I have them. . .


So. . . another local guy is selling wheels off his IS350...

Front 19x8 +40

Rear 19x9.5 +40

2 questions:

1. Will they fit? Rolling required in rear? Camber required? I'm slightly lowered on H-Techs, but plan to go lower in the future.

2. Hub Bore size. . . other than having this guy measure, is there a way I can tell if I need centering rings?

Thanks again.

Im looking at getting some rota boost 18x10 offset 30. will this fit and what tire size would you recommend. i have tien s techs right now but plan to eventually put on a full coilover set up

You will need a roll at the minimum. Search for user thejew89 he has this setup.

I am getting the same specs soon and will probably run 245/40s to begin with and may try 265's later on
