Just installed 5mm flat bar at the bottom of Lancer EVO8 Recaro seat. I need to drill a adjustment hole on the original seat rails.  

Bad picture, but they fit. I just need to mess with either making new sliders or modding the stock ones to fit on these seats. They are out of a ZZW30, 3rd Gen Toyota MR2

These are '95 Prelude seats on our 280z and they fit fine. The cat hump required some reshaping (*ahem*) but the seat  fits my 6'1" frame fine. We used the stock Datsun runners bolte

This weekend Capt_Furious and I installed NA Miata seats into his early 260z. I know there are other Miata seat posts in this thread, but hey, why not add more of the same :)

 

Picked up a pair of NA Miata seats with rails for $100. No major tears - just some usual wear on the driver's side bolster, but no holes or major tears. These have speakers in the headrests, so the wires were cut hanging out of the back. They were dirty and got a decent cleaning from a wet-vac (I needed to rug-doctor the carpets at home, so... this worked out).

 

No photo description available.

 

Miata seats rails. The spacing between stock Z rails and stock Miata rails is about 3/4" difference.

The guide pins and mount tabs are riveted in, so they had to be drilled out and they pop right off. The mount tabs on the other side were cut off.

We used the guide pin hole as the reference point and drilled new holes in the back of each rail. M8x1.25 45mm long bolts were welded in so they wouldn't spin. These were regular hex head bolts and cleared internal rail guts just fine.

When we removed the driver's side seat, we found that the mount tabs were cracked/torn. The rear mount plate fully separated at the spot weld and had a huge crack, so I welded in 1/8" plates to fix this. Ugly but functional.

Drilled new holes off a cardboard template I made and the seats went in like butter. The seat height is taller than stock and the headrests are lower than Z head rests, despite the seats looking to be of the same height.

The ol' MK I calibrated butt dyno says the car is MUCH faster with the new seats.

 

We all know that's a lie.  My keister's been lying to me for decades.

 

But, I'm much more comfortable and confident than I was with the nearly 50 year old factory seats out of aux's 240.  That's got to be worth something.  With the mounts fixed and the newer seats, there's much less perceived shake / rattle, and the bolstering is what I'm used to from my much-maligned and departed '94 Miata M Edition.

 

A drive up Suisun Valley, into Wooden Valley and past Berryessa on Saturday had me pushing the car in the turns much more than in the past.  Thanks to all of aux's boredom and hard work during COVID, new suspension, tires, and seats really make for an improved ride, even if much of it is perception.

Its interesting that you fellows have a positive impression of the Miata seats.  My daily driver is a 1991 Miata, and while the seats are functional, they aren't exactly the highlight of the car.  In the Miata community, tossing the stock seats and replacing them with something aftermarket, is a common practice... first for more support, and second to save weight.  Yet another alternative is the "surfboard" (high back) seats from the NB2 Miata.
