theres nothing wrong with using a wheel spacer.

the fact is your wheel company probably doesnt make the wheel you bought with the offset youwould need to make it work.

wheels are made for common offsets...FWD car offsets for the most part.
30, 38 40, 48 ect

That did come across as stupid, and Kenny was right on the money, all the brakes in the world wont do ***** without decent tires and wheel combination.

advan racing 2 different models,
SSR mesh= lighter
watanabe rs-8 =a little lighter but much better looking
watanabe 8 spoke (originals magnesium) = much lighter, way cool looking, but prone to cracking after extended road racing (4 seasons)

these are the ones I can think of, on the top of my head, and I know that there are plenty of others.

lightweight wheels bend alot easier though.....personally i love the look of the 2nd gen BBS. The only reason i would buy custom wheels is to put fatter tires on.


Is there any modifications needed to fit TII brakes in a 15in wheel?

I have changed the spread sheet to make it easier to figure out.

Change the variables in red to find the Offset needed and Possible spacer needed.

Looks like the bulge of the tire is where the stock wheels are hitting. The first row in the spread sheet is based on the convertible wheels.

I have measured tire bulge on a few wheel tire combinations and it seems like they vary from 1/4 inch to 3/4 inch depending on the tire size and wheel width. None of mine bulged more than 1/2 inch. The numbers WoodOnaStick posted suggested his bulge by 3/4".

Hope this helps. Really what is key is you do not want more than 5" backspace including the tire bulge. Anything less and you will need a spacer.

15m inch wheels

" Is there any modifications needed to fit TII brakes in a 15in wheel?"

I think the 2nd gen brakes will fit inside any 15 inch wheel. I also agree that the BBS alloys are nice looking, though not nearly the modern "radical" look some people prefer. A lot of people have commented favorably on the way they look on my car, but mine is definitely a "sleeper". If I had a really fancy, bright custom paint job, I would want some really fancy bright wheels.

An interesting issue is the need for larger wheels in order to get the best handling. Certainly the 15s give you better tire choices than the stock 13s, but now even the 15s are limited in tire choices compared to the 17-18s. I definitely noticed a big improvement in acceleration, braking and cornering traction with the tires I have on the BBS 15s, and I really needed more traction with the torque of the V8. I am pushing the limits of tire clearance without modifying the stock fenders. My suspension is stock except for some good shocks.

No doubt there are better performing tires out there for the bigger wheels, but then you are talking about very low profile "rubber band" tires, and I think the ride may get pretty harsh for a daily driver. And I think you would want to do some suspension mods to a 1st gen to get good results. The suspension of a 2nd gen car is much better suited to really wide low profile tires.

I have no personal experience with anything lower than 50 series tires, so ask someone who knows.

i feel exactly the same way. Aren't the TII brakes larger than the other models? I thought that was why the TII had 16in rims, because of the larger brakes. If they could fit inside the BBS rims that would be amazing

As far as the tires....I have a gsl-se which has 14in rims with 205s. The BBS rims come with a 205 stock also, but i could fit a wider tire on them than on the -se rims. With a non-turbo, stock port rotary i don't have to worry about torque and a 205-215 azenis will do for me on the autox and track

ok i got it to work after installing excel.

after looking at the graph...im even more confused. im sorry but that chart just totally went over my head.

i just need to know what 2nd gen wheel(or the width and offset combination) will fit without a spacer and what size tire is needed also.

You would need 5" or less from the bulge on the tire to the wheel mount.

do you have any idea what offset that is with a 7" tire? i think 7" would require a lot of lip that may stick out of the fender well. my problem is that i dont have a problem running a spacer, but i just want to mess up and end up with the tire sticking out of the fender well. i think i need to learn how to interpret offset a lot better and i should be able to figure out what to do.

what wheels did fit that would be the question at hand
like a 7.5" wide 16" wheel what offset would you need. could yall possibly post up a list of needed offsets with what width wheels. or just post what backspacing is needed then we can figure out our own offsets we need.
i plan on buyin this kit next month after xmas im buying wheels after that so im not worried about a different offset but i would like to know what i needed.
thanks

possitive offset is the measurement from the center of the wheel to the wheel mount flange.

i just thought of something that should have been clear at the beginning, im not that smart sometimes, but
you need to buy wheels that have the offset for a first gen and not a fc, so you need to see what the stock offset and backspace is for the fb wheels and go from that. i think its alot less than a fc is. that would be the reason the fc wheels wouldnt fit

Learn to Read !!!

I can't believe this forum is populated by so many idiots. All the info you need to figure this out has been provided at least once in this thread. If you can't figure this simple problem out by now, you should not be making modifications to your car. All you need is a straightedge, a measuring tape and a brain.

not rough, its called being honest Seriously though some of the people need to think before they hit the enter button as some of the questions are truly of the elementary level (yes the forum is a place to learn but either serach, or if you can't find it direct PM a person vice embarrassing yourself) Stilletoman just doesn't have as much restraint as some of the other members
