Triumph TR6 - seat fwd/aft movement

Do the TR6 seats (74) really stop forward of the rear shelf? Mine are like 3" fwd of the shelf at what appears to be their furthest aft travel....this seems like a huge waste of leg room. I'd love to get the seats back another two inches w/o sacrificing safety or switching to "miata" seats.

Take it back...it's more like 4" to 5" fwd of the shelf!

JT, the aft travel is limited by the "stop" on the seat frame bolted to the floor. You might be able to "adjust" that stop, reduce it or remove it and replace with a bolt or some other affirmative stopping mechanism. That'd give you another 2-5 inches of rearward travel, I think.
Doug Baker

Couldn't find any "stop" BUT just through lubricating the rails I was able to get a goo 1 3/4" further back which made a big differance in sitting position.

JT: I had my seat rails re-done/repositioned as per Kitchener Charlie's recommendation since I am a normal Canuck height at 6' 4". I'll try to find the thread and let you know where his specs are. He provided pics and all.

Basically, length was added to the front of the floor mounted rails and they were re-positioned towards the back another two inches allowing more travel for the stock seat within the stock adjustment allowance.

Now my knees do not block my view. ;)

JT... I checked archives and found entries by Charlie B. (the king of the long leg solution) but the links to pics were dead. It's out there somewhere. Just keep checking enties under Seats, Miata, and other variations. Once those seat rails are moved back the seat will follow and life will be good. That is unless you are 6-4 like me then it will be suggested that you have surgery to shorten your legs.

Ken you need a Wedge. I'm 6 foot and I have the seat about 3/4's the way back

JT,
The modification Ken describes MAY be on CD II. I'll have to check. If not there, I may still have it in mr TR6 library. I'll check tonight and advise. The seat travel is limited by the movement of the top of two superposed rails interlocked on two rollers suspended on two O rings each, but aft/fwd travel is limited by a dimple in the rail that interferes with the roller. You could possibly move that "dimple" or stop further aft by grinding it out and then inserting a bolt or redimpling the track OR reconsider my post above about the rear stop that affixes to the top bottom rail and "stops" the rearward travel of the top rail. That may not gain you anything w/r to rearward travel though cause it's only there as a safety stop. To reposition the rails as Ken suggests may offer the greatest potential for claiming more of the available space. BTW, I discovered that my O rings had flattened with age and use and acquired replacement with the advice and asssitance of Steve Pike to refurbish the original rails. I successfully disassembled my 4 double rails, bead blasted, powder coated, replaced the O rings lubricated liberally and reassembled. Had to fashion a new stop in place of the dimple 'cause I had to remove that to get the rails apart. THEN TRF had a "give away" sale on rails so I purchased new ones anyway!@! Now I have two sets. If your seat travel seems a mite stiff or does not move easily, consider replacing the O rings. Good luck.

DK... I'd do a Wedge if it t'were V8 powered and had aftermarket hotwheels and tyres. I'm not a fan of the design but I could be talked into power that excedes my TR6. On second thought, maybe I'll get a divorce and take the kitchen scraps I'd end up with and buy a 427 Cobra.
Ken Shaddock

Thought the same thing till I drove one.
That's all it takes. Have you seen mine?

V8 with a programmable Gm ECM .

My 86 XJS, V-12 satisfies my "need for speed" (plenty of leg room too!)

Doug... I tried to look at my copy of CDII but this new laptop does not have the necessary software to deal with .rar files. Where are the Geeks when you need one?
Ken Shaddock

Googgle that term and you will find a free download
DON KELLY

Ken and anyone else interested, post or send me your email and I'll send you Charlie's article. All he really does is effectively mount the seat frame about 1.5 inches aft.

I've done what CB recommended Doug. I was looking for JT.

Personally I now sit on the rear shelf where my speakers used to be. The speakers are on my luggage rack. The soft top and its frame hurt my back but hey, I can see passed my knees. Sorry, I was in the mood to mock myself and got silly.

New surprise with the car. The left front now has noticeable negative camber. I had been working on details like finding squeaks, replacing the speedo/odo cable, bought a new bearing/bushing for the steering column to stop my steering wheel from wobbling and the freakin horn from blowing and now ta-da... my left front looks like I'm ready for clockwise oval track racing.

I love my LBC, I love my LBC, I love my...
