lol shit.



Been there.

Thanks for all of the good vibes. This all came from the idea of putting the V6 in the car and spiraled from there.

"I'll need more tire."
"May as well do widebody"
"Well shit, I need 5 lug"
"This won't look right without a hardtop."

And now have too much going on with it.

thumbs up on all acounts except for the 5 lug shit. You're going to be nearly just as shit-out-of-luck on wheels with 5x100, unless you're planning on converting to 5x100 and then using conversion spacers to go to 5x114. But that just seems retarded. Everyone with a 5x100 car hates it and converts anyway.

Seriously, just fucking get conversion spacers. From four by fucking one hundred, to five by fucking one-fourteen.


Dont take anyones advice on wheels or anything. This shit is 100% Kevin's rad as fuck vision, keep it that way. I wouldnt even WANT to suggest wheels, I want to see what YOU put on this motherfucker.

You guys are the only people who have seen real updates. The fenders are mostly done. The fender to bumper gap sucks, so that needs to be remade completely. I had to make a handful of brackets for mounting tabs that are no longer there. I now need to build up some of the panels to make the gaps a smoother transition. (hood to bumper, hood to fenders, etc)

I picked up fiberglass sheets for the quarter panels. This saves a LOT of time trying to make something flat. The front wheel wells have been recut higher and they now have about a 26" diameter hole for the 18's. Test fitting wheels this weekend to see what ultimately will go on. Wheel arches will be finalized after the wheels and tires are finalized.

The front has been lowered until the collars bind. The rear is still at the old height, which will be fixed soon.

I'm also pretty sure that I will be smoothing out the naca duct and the antenna hole on the passenger quarter as well as the turn signal indicator holes on the fenders.

That aero is so crazy.

Seriously, so much fiberglass work. If I had one of these, I would totally buy this kit, then realize its going to cost more than the kit itself to get it to fit right, then sell everything.

But im super psyched on it, any pictures of how the rear quarter "curves" look on an already assembled car with it? I want to see if its really that much worse than the flat surface youre after.

naca ducts are cool.

Thanks dudes! I get more and more excited as it comes together.

The first pic on the last page shows it best. Hard to see because it's black, but it's there and it bothers me. It's either live with it or fix it now. I choose to fix it now before paint.

In other news, my hubs and bearings came in.

Sorry if this doesn't make much sense. I did a write up on the MRS forum because dudes have talked about this for years and no one ever jumped and did it.

Some old data I gathered prior to it all:

Wheel Bearing:
2002 MR-S (rear bearing) --- 2002 Celica GT/GTS (front bearing)
Outer Race Radius - 0.0591" (SAME)
Bore - 1.5748" (SAME)
Outer Diameter - 2.9134" (SAME)
Width - 1.6535" (SAME)
Inner Race Radius - 0.1378" (SAME)

Hub/bearing assembly:
Spyder (front) - Celica GT/GTS (rear)
Bolt Quantity - 4 ---- 5
Flange Dia - 4.921" ---- 5.31"
Bolt Circle Dia - 3.937" ---- 3.94" (rounded spec)
Wheel Pilot Dia - 2.126" ---- 2.13" (rounded spec)
Brake Pilot Dia - 2.1654" ---- 2.17" (rounded spec)

Brake Rotor diameters:
Spyder (front) - 10.04"
Spyder (rear) - 10.35"
Celica GT/GTS (front) - 10.825"
Celica GT/GTS (rear) - 10.585"

What all this means is that YES, the front of the Celica and the rear of the MR2 share the same wheel bearings. YES, you can press in a new bearing and Celica front hub into the rear knuckle of your MR2. NO, the Celica brake rotors wont fit without modification. To get around this, I carefully measured and drilled new holes. There is still plenty of clamping material on the rotor around the studs. I do not foresee this as an issue, but I will watch it closely for now. I will try to find drop in rotors already drilled to 5x100.

Now, regarding the front. YES, the rear Celica hub assemblies will bolt to the front of the MR2. NO, you cannot use Celica brake rotors. You either need to redrill the rotor or find a different rotor.

$300 worth of Rockauto parts (I went with high quality Timkin bearings, this can be done cheaper with less expensive parts) and $15 worth of beer to pay for the bearings to get pressed in and here it is.

Rear bearing and hub pressed in


Don't mind the surface rust, the car has been sitting for awhile. You will see that the rotor drilled to 5x100 by a shaky Russian hand but it is centered on the hub.


Now, if only I had some wheels...

Any luck with wheel choices?

Fuck it.


White Segamasters.

I'm still looking.

I'm trying to buy something reasonably priced, since my TE's still haven't sold. Today I found that an effective 18x10 +25 will fit in the front (the front would be very tight, so I may opt for a 9.5 for driveability's sake) and the rear can fit 18x10.5 +20 to +25 before any modifications. The car is currently 5x100, so a 15mm 5x100 to 5x114.3 adapter will be needed.

I'm currently looking at a set of TC105n's in 18x9.5 +35 all around with 15mm circuit sports adapters. The slight difference in offset can be accounted for with alignment or fiberglass.

This S2000 has 18x9.5 +35's on it. Face isn't concave like the 18x10 +12's, but I don't mind it but they seem a little plain. (Which is why I haven't ordered anything yet)


I've been watching Zilvia, ft86club, NASIOC, and S2KI for wheels and the used market sucks right now.

Oh, and I'm pretty sure I want black or gunmetal wheels. The car is being painted super white, but I think I said that before.

I actually like the 9.5 more than the 10.5 in TC105n.

Good luck finding wheels in the used market place dude. I mean it'll probably be easier and probably come out costing the same if you order them new from like TF. Used wheels prices are dumb right now, people asking 1k+ for XXRs and Varrstoens

^Yep.

Used wheel prices have doubled (or more) in the past two years or so.

TC105 are sweet.

Just me thinking out loud. The more I look at these, the more I like them. I'm not sure if I can pull off the bright yellow, but maybe. Good sizes at a good price, plus I can sell to S2000 guys when I'm done.

Those tc105n's will look decent. Sigh.
You should have just went single lug like a sick ass nga.
Could've been torn over either having to buy magnesium te37 or some other cray ass centerlock shit.
Now you out here wondering what kinda goof-cock, humble-boy 5 luggers to buy.

Tsk tsk tsk tsk.

I haven't ordered anything yet. I've been searching to TC005's, but they've been eluding me. Trying to stay under 2k.

why did you go 5 lug if you are still going to use adapters?

Do you have tires picked out? I cant see this thing running anything other than super wide R-Comps.

Because 4 to 5 lug is sketchy with the amount of mechanical grip I'm aiming for. I talked to a few owners of 4 to 5 lug adapters and they all hate them. A 5 to 5 is exactly like running a normal spacer. The 4 to 5 has a shared lug or some stupid intricate two piece spacer design.

Looking at A048's and R888's right now. I'll make the jump to R's later when the bank account fills up again. Widebody, paint, 5 lug, wheels, and AEM have all taken a huge impact on the wallet this year. Not to mention the V6 stuff that I've started collecting. With only one set of wheels for the car right now, R comps are unlikely. I don't want to wear them down driving once to the city and back.

Aren't A048/R888 R-Comp, you mean AD08R & R1R? I'm lost with the way this is worded.

I'm under the assumption to that A048/R888 are not R comp, are they? I know so little about tires. I always thought R comps have no tread pattern, but may have a line or two.



Anyway, I bought wheels.

R888/A048 are R-Comp, the Z214/Hoosiers would probably also be considered R-comp, probably comes down to treaded R-comp vs. semi-slick or something.

What wheels? Don't be a lame.
