DSE Tillett Racing Seats and Brackets

[Tamvette]

I believe a slight shim is needed if using the slider. It's to allow clearance for the slider's locking mechanism to unlock. Otherwise, the lock contacts the seat's side bracket and won't release.

Doug suggestion to position the slider on center between the top and lower half of slider worked for me. With the slider in this position it reduces the amount of play within the slider between it's upper and lower half. Even in this central position, there is still some play although considerably less. What I found while on track you don't notice any play when you're strapped into a harness.

Quick update on this, I removed extra shims and test drove the car. While it improved the stability, it was not as stable as I wanted. I ended up removing the slider and directly bolting the seat. I didn't have a chance to drive it yet but the height drop made the sitting position better for me.

Seat feels nice and rigid, can't wait to test drive tomorrow. Now need to wait for the passenger side bracket

Did you drive with a harness fastened, which makes a huge difference?

Doug,

Quick update. Spend the weekend on the track with the new seat base installed on the B6 XL screamer. Even with the slider the seat felt stable (key is to insure your 6-point harness is very tight). We worked the TA overtime(multiple run groups) between my brother on Saturday and Sunday with a freind, who ran out of brake pads on his vette. The slider came in handy to accomodate our differences.

Side note, the proper size seat matters beyond simple fitment, in the XL I noticed needing to reposition my rear sides to improve bracing and chassis/tire feedback.

I am sure it would but I wanted the seat to feel rigid on city driving as well. I only have my brother and my racing teammate drive this car occasionally and they are both close to my height\weight so fixed is ok for now. I am not sure what will happen if I ever need to go to the dealership though

You guys are making it incredibly hard to be patient. My seats should finish up this week then head this way!

For anyone around 6' 2 and 200, while I am sure fit will be different for everyone, I finally settled on mid point in the front and drilled a new hole at the top of the rear side of the side bracket (tbf1). Did not use any additional spacers, now waiting for the passenger side.

Curious which harness is everyone using with the tillett and DSE seat base?

The teamtech Rampac was great with the OE seats, since moving to the Tillett and DSE seat base, it requires moving the lap belt adjustment buckle to inside the seat to allow access to tighten and release the strap properly. This created another problem with the buckle resting at the pelvic, occasionally pinches. Seems to be a narrow window of adjustment from being in the perfect location vs not.
I'm considering moving to another harness like the Schroth Enduro 2x2 or 3x2. The Enduro lap belt adjustment buckle appears better suited to the Tillett seat design. With the buckle adjustment located close to the center allows easier access. The 2" lap belt could be a better fit.

I installed Schroth Profi II ASM with the seat. I test drove it today with the harness and it is a good fit. With the ASM harness, you can either use it 4 point or 6 point. I honestly never used a 4-point harness before and it didn't feel as comfortable as the 6 point harness but my brother thought I was imagining things.

Just to note, would have to install "PROFI II ASM FE" to be street legal.

I assume you install the seats onto the brackets and then mount inside the car? If so, and assuming you mount the seat as far back as possible, how do you ever get your hands in behind the seat to install the rear bolts? (seat bracket to car frame)

You should still be able to access the 2 rear bolts that fix the bracket to the chassis. It requires a bit of dexterity if the seat is right back on the brackets but should still be possible....

And thats exactly how you cross-thread and damage sh!t. Im sure it was a joke

There is space to start the nuts with your hands and tighten with socket wrenches. The seats will touch the bulkhead at the headreast before the floor so there is more space in this area. Many successful installations in the rearward position.

+1 to Doug.

I had the same question. Installation was a breeze. Seats look, and feel great.
