I have been doing alot of research on my new choice of wheels, I currently have enkei aegis which are for sale. My new purchase is going to be work termist tm1, who I will be ordering from Rishie at autornd.com. If i must say anything about him, his customer service is the BEST I have ever expirenced. I have done business with alot of rx7 companies, and his dedication and service far surpasses any one I have ever dealt with. He reccommended me:

62mm front(18x9) and 77mm rear(18x10), with stock brakes (stock fenders). I dont plan on upgrading the brakes, maybe coilovers in the future. Anyways I would never doubt him, but I have been doing a lot of research, and it always seems that front offsets are in the 35-40mm range, and the rears as close to 50mm. I never ever heard of anyone with offsets above 50mm. My goal was to have the biggest lip possible with out the rears sticking out, obviously I would need the fenders rolled. Just looking for any responses, all rynbergs and speedkings response have never reccomended offsets abot 50mm. Just curious on your though, I will be ordering these wheels from Rishie in the next few days. BTW, here is a sample of what they look like, they are 9.5's in the back.

 

hmm are you sure that the mm numbers he gave you aren't the size of the lip instead of offset? that would seem more likely.

 

offsets are all relative to the width. those are fairly wide wheels, so it doesnt put it beyond plausability.

on the other hand, i don't know FD wheel sizing at all. it would help if i actually had an example of what is 'flush' on a FD and what has proper inside clearance.

 

Those numbers don't seem right. I have +38 18x10 in the rear and I am fairly close to the trailing arms. +77 is over an inch further inboard. Maybe it's another measurement, although I don't know what it would be.

 

As was said above, Rishie was telling you the lip size. Rishies done enough FDs to know what works.

18x9 +45 has a 62mm lip in the standard disk (A disk) - which would clear the stock front brakes. Using the matrix, the 18x10 with a 77mm lip would either be a +43 offset in the standard disk (A disk), or +50 in the deep rim disk (O disk). (The size matrix gives a max and min offset with corresponding lip, so it was a matter of simple math to determine offset/lip size combos in between.)

All three (the single front and two rear) are perfect for the stock brakes. If you have or plan on getting a big brake kit, then you would need to use the 'big caliper' disk centers, at least for the front. Rishie knows that, but picked the disk centers with the deepest lip (since that was what you asked for), given that you said you have stock brakes.

 

And so that the misunderstanding is not perpetuated, offset is dependent on wheel width. An 18x9 +35 is a very different thing then a 18x8 +35. You cannot specify an offset without the corresponding wheel width.

 

I agree...it sounds like Rishie was looking at the rim lip column.

Quick question. If you put a +40mm offset (big brake) in the front and put a +50mm (deep dish) in the rear, won't your rear wheels be further in than your front ones? If so, won't that cause handling problems with the front wider than the rear?

 

+40mm and +50mm

your question is unanswerable because you did not state width of the wheels

 

sorry. Assumming the same width, they wouldn't be in line. Would a 18x9 in front and a 18x9.5 or x10 in the rear make it in line?

 

that depends on what you mean by "in line"

do you want to keep the inside clearance the same
the center of the wheels in line
or the outside clearance the same?

if you just want to keep the center of the wheels in line, you run the same offset on whatever staggered widths you choose front and rear

for instance 18x9 +40 and 18x10 +40 would keep the center of the wheels on the same line

the 18x10 would have half an inch less clearance inside, and extend half an inch more outside, relative to the 18x9's in front

 

yea that's basically what I meant. I just want to make sure a +50mm in the rear on a 18x10 (or x9) wheel isn't going to be further in towards the car than a +40mm 18x9 wheel in the front. Otherwise wouldn't you be running kind of a reverse stagger with your front track wider than the rear?

 

that depends on your particular combo

18x9 +40mm F
18x9 +50mm R
your front track will be wider then your rear by 10mm on each side

18x9 +40mm F
18x10 +50mm R
i beileve your rear track will be wider then your front by 3mm on each side

as you can see, offset doesn't mean much without width

 

okay thanks. 3mm isn't too much. So if I get 18x9 +40mm F and 18x10 +50mm R, then It should have a deep lip in the rear and be able to clear 99 spec brakes right? Just confirming.

 

deep lip totally depends on what wheel you pick. i can think of a few 18x10 wheels that are flat spoked with no lip at all.

i have no clue whether it will or will not clear your brakes! better get one of the auto rnd guys in here. lol.

in my experience, brake clearance usually depends more on spoke design then offset (although offset DOES matter)...

in other words, pick a particular wheel first. then choose sizing and see if it matches up with what you want.

 

thanks for your help man.

 

what size tires are you gonna run?

i think the vertex demo car is running 17x9 +29 and 17x10 +35 how much lower can you go with or without roll'n the fenders?

 

Here is what Rishie said when I pmed him about it:

This will work with coils, no problem. As for the lip depth you're thinking to hard. Because the offsets are custom you need to look at a different column on their and calculate the lip depth. It calculates to be exactly what I've indicated. Don't try to figure out too much or i'll have to teach you my 10+ years in builing custom wheels knowledge. lol.

How much are you going to sell your old wheels for? Pm me

 

Also note that while you might prefer not to have a wider front track than rear on your road-going RX-7, many cars, including purpose-built race cars, have a wider front track than rear. It isn't handling poison.

wow this is my car and i am now selling my wheels. if anyone is interested, the front and rear offset is +38, 8.5 in the front and 9.5 in the rear, the rims come with new tires with 98% tread life, all rims in great condition. im located in the Woodlands Tx. asking $2,000 not shipped. firm on price

 

Ok wow, i can't believe i didn't see this. So just for clarification the offsets you think I recommended are actually the

LIP DEPTHS. not the OFFSET. Your offsets will either be 9" +45 and 10" +45 or +50.

BTW, thanks so much for the compliments. I am most gracious. Just wanted to make sure that guys know i wasn't misleading you.

Thanks, Rishie

 

FYI, i love you guys. Ted, Dan, all you old school guys. Thanks for saving me some humiliation by snipping the misconception in the bud. Thanks a lot guys. Never will there ever be a group of guys like you on any other board. I have never found such a dope community of owners. Rotaries rule and so do their owners.

Peace, Rishie
