Seats and seat rails

[thenixtone 4]

Hi everyone, I'm looking at some new custom seats for my R34 GTT.

I spoke with Autotechnica and they said their seat rails will not fit, waiting on a response from Velo.

 

I don't really care on brand, I want something ADR approved though, I've heard a few whispers about needing ADR approved seat rails, is this a myth or is it true? (specifically for QLD, nothing on TMR website is vague)

 

Anyone have a combination of seats and rules that is legal / will fit without much f**kery? Cheers! e.g some weird ebay universal seat rail that would fit autotecnica seats

It's actually really difficult to do this legally. Precious few aftermarket rails are legal without being engineered. Same with seats. The cheapy eBay Brides and other similar seats that claim to be "ADR" approved are frequently the shittest quality, so the whole ADR thing must be a massive lie with them.

Probably the only sure fire way would be to enquire of an engineer in your state about what's required. I'd say that going to a motor trimmer and getting Recaros + rails (for lots lotsa $$) would have to include whatever engineering signoff was needed. You could try asking them.

Just to help out, not sure if you are even still looking into this @thenixtone

 

i bought the autotechnica ssp67 seats

i bought the autotechnica seat rails and

these seat subframes from crank Motorsport:

all bolted in with no issues at all, no drilling, just bolt it in

Again @Tobz I have a question, as I have a 34 and had to make my own seat "adapters" (i.e large steel plates with huge bolts)

Do the ones from Crank Motorsport raise the seat up much/any? I found that after making some plates up the seats did sit a fair bit higher than they otherwise would have. An off the shelf adapter like the one you listed would have made my life a lot easier!

In any case thanks for posting, people often have R34 problems with seats fitting and end up having to buy rails that do/don't/maybe fit, so getting the info out there is 👍👍👍

I found with the seats, rails and crank Motorsport bracket, my seats are actually lower than stock now

Also I think getting it low requires a bottom mounted seat, side mounts add to much height

Looks sweet!

I’m keen to put these in my s15.

How is the lateral support? Any good for track use do you think?

Better than stock, not like a real bucket seat though, heaps more support than stock, heaps less than a dedicated bucket. I think it will be good enough, especially with a harness

Thanks.

Thats the main aim, looking for something relatively stockish looking, that I can use with a harness at track days. 
this seems a good solution.
