Sparco R100 seats installation

[thornado327i]

I've posted this in the "interior" section with no replies, so I figured I place it here (sorry for multiplying the post, but I would really like to hear some opinions).

I have a set of Sparcos (R100) to put into the car, and I'm thinking about some brackets.

The seats:


Here's what I came up with (behold my MS Paint skills ;-)):

Basically it's an idea to widen original Sparco sliders (rails) and use thick-walled aluminium bars that would act both as bolt pattern adapters and risers. Next, two more bars to link sliders-to-seat mounting holes in which I'd drill the holes to bolt the seat onto.

By taking some quick measurements I found out it would work fine, but I'm not sure if it's a good solution safety-wise.

Any opinions (well, almost any) are welcome. I plan installing the seats in about a month, so still plenty of time to think.

That small handle is not going to affect safety if you make it wider. The brackets are your safety concerns if you modify the bases. They are what keep you in the car.

If sparco makes a seat adapter for the e30, I would recommend just getting those. Remember, if you wreck and your seat breaks loose, you're a goner.

If they don't make a seat adapter that will work for you, then make sure you overbuild the f*ck out of them.

What I had in mind is:
1. Placing the sliders wider apart (then the manufacturer intended) by app. 8-10cm
2. Using aluminum bars (3 or 4mm thick walls)

As opposite to:
1. Aligning sliders with the bolt pattern on the seat
2. Using steel bars instead of aluminum

EDIT: Sparco does make an adapter - I have some doubts towards it though - doesnt' look well designed.

3mm thick aluminum? Really? ;-)

3mm thick aluminum? Really? ;-)

Meaning a bar... how to put this... rectangular x-section bar?

Excuse me bad English speak ;)

So I mean a bar which walls are 3mm thick.

Better?

110 USD each - that's quite a price...

I think I'd rather make my own brackets. So back to the question about my approach.
