Kaminari fitment is not great. Kinda disappointed in that.

Looking good to me. what’s the problem?.
Mounting holes are off by a significant margin. I had to dremel away sheet metal in the hatch. Some holes were off to the rear, others to the front. The wings can't use both threaded mounts without a LOT of dremel work. I have them installed with just one right now and will likely leave it like that to minimize the surgery on the body.

The wing tips don't hug the car very well. On the driver's side, the tip is like 1/8" away from the car body. It's just not molded similar enough to the body when mounting holes are aligned.

The rear curvature of the hatch is not matched by the wing. The hatch has a curve, the wing does not. So you end up with this weird, obviously aftermarket, mate that just looks off. That's only noticeable with the hatch open... I think. But still... I don't know. I like the overall look a lot, but the quality/precision of the part is not good.

It's my fault for not checking fitment beforehand. I was rushed in the whole job and didn't really have the time to attempt fitment before paint. Not sure what I would have done anyways. I'll document more on that later. I shot video of the issue.

I feel that this is a problem with aftermarket mass produced parts, even if modeled off of one car or a couple cars you cant assure that the parts will fit a big number of supras due to manufacturing differences which leads to fit issues on some cars.

If my mass produced unbent, clean, original OEM spoiler parts slip right on and off with perfect alignment, I expect the aftermarket part to do the same, plus or minus the mounting hole tolerances. The mounting holes are generous, too. We're not talking 1mm clearance holes here. The sheetl metal in the car allows like 3X the bolt diameter to clear through. The Kaminari spoiler is that far off and then some.

I don't know, but I can't imagine the sheet metal on mk3's has varying hole placements in those stamped parts. The spoilers from the factory didn't need any tweaking - why should aftermarket parts?

My thought is that the shops doing aftermarket parts like this generally don't take the time and energy to engineer every part to perfection and just say, "Professional Auto Body installation required" and let the end user sort it out. In reality, this should be a plug n play part.

My right front side molding isn't secured yet because of the Kaminari front bumper fitment. It's either getting up under there and doing some body work, or trimming the side molding with a razor blade. I'm not one for butchering parts, so this job lingers :(

That seems so crazy to me that an established company would have fitment issues like that, but it's a recurring theme in the aftermarket auto world. Makes me think there's a massive hole in the market for a properly engineered parts manufacturer.

Now I dont know if this is 100% true and it should completely be taken with a grain of salt but I have been told that the turbo cars were shipped out of the factory without spoilers and it was a during the PDI that the spoilers were put on there just like newer model camrys that were optioned to have spoilers, but they were dealer installed. But yes, I agree all the cars should be the same and the part should fit all the cars if the time was taken to properly R&D the part before release.

I don't think that's the case for 89+ at least. The mounting holes were painted with OEM paint along the inner edge of the holes. If the spoilers were added after factory, I think there'd be a visible touch up paint line on those holes. Looked like it was part of the stamping and the holes were present before initial paint.

There are two separate part numbers for the TWC (NA) and Turbo (TWT) as well. I think the only difference would be the spoiler holes.
