Bucket seat prices

[r.ave]

Great advice so far allready.

There are however still steel framed bucket seats with FIA standard as well (Sparco sprint, Ltec Pro), but as Ivan already suggested, they are not the most comfortable ones, but they are cheap.
And there are several seats that would do the job without a FIA standard as it would be mainly for street driving. (QSP)
Another advice, don't buy online without testing the same seat in real life.
Go to a shop where they have a variety of brands and models and let them advice you.
As you need to sit tight and comfortable at the same time. The position of the holes where the shoulder belts go through need to be on the right place (deff not too low)
Some shops: Biesheuvel (Nieuwendijk), Autosportcompany (Waalwijk) or a little more close to you Hoogstra Autosport in Zuidwolde (They have beltenick)

Even though the AE86 lets people fit up to 1.90m (me) easily, with bucket seats its not the same.
I had a hard time finding a seatframe for the Left hand side that would fit a bucket for my size. Then you can't go low enough due to original mounting positions.
I'm not using a slider, otherwise the seat would have been higher and my head would have hit the ceiling.
I have a Recaro Pole Position fitted with a Nisuba seatframe (available at driftworks in the UK, but maybe it would be better if you buy directly from them in Spain as it saves you import taxes)

I still have a red East Bear seat available, you are free to come buy and testfit it. However, it's quite narrow and i did not fit in it (nor do I fit in Sparco seats as that's for small italians)
