Aftermarket "racing" seat prices

[nando]

there are some decent china knock off seats out there but you cant take them to the track.

uh, doesn't that pretty much defeat the purpose?

JGood,
Why not attach it on top of the carpet? The carpet thickness at the mounting mounts is nonexistant, no?

Also, what method did you use to line everything up and drill? Put the stuff together then drill pilots from the bottom?

Found some pics. Do not install it on top of carpet like I did. I just did that to get the car back together for an autox, I'd never go on the track with it like that. You'll notice I drilled the holes wrong, so I still had to use spacers between Lee's mounts and the angle aluminum. I've since corrected those flaws. Expect to spend 3-4 hours on the install.

"Massive" stickers are supplied in white or red. Shipping is $25usd to West Coast for one set. $30usd for two sets.

FIA aluminum seat mounts are 6mm thick. Massive's are 6.35mm thick. The base plates can be 1/4" extruded stock and it will be very strong. If you use th OEm sliders, don't weld them. And BTW they are very strong.

Having a shop build you a custom install usually takes about 4 to 5 hours, per side. Lotsa thinking, cutting, welding and drilling. And it costs a lot. Which is why I came up with Massive's sidemounts. At least it allows anyone to do his own custom install, easily. Fixed or sliding.

I may be contacting you soon about some side mounts and the slider adapters. Do you have a price range for both of those pieces shipped to SoCal? I really like the black side mounts with the red MASSIVE logo. Pure sex

Gotcha. Yea, those holes do look a little close to the edge of the angle. Couple of roll overs with 200+ lbs in a seat and it would likely fail.

Maybe Lee can make adapters with an integrated base for an E30?

Or how about welding the factory sliders so they are in a fixed position?

Do a google search for FIA approved 2 piece side mount brackets......Those brackets are all extrusion and strong.

Why would you weld the factory sliders? If you are going to use them they may as well slide. It's not like the factory slider moves inadvertently

I don't know, that's Lee's pic. I forget what size I used, but it looks the same. It may be better to go with steel, I'm not sure about the strength of angle aluminum. Anyone else know? I guess it depends on the manufacturer...

There is at least one FIA approved two piece side mount.....

Aluminum like the angle is an extrusion. That shit is usually hardcore stong

Yep, I was in agreement about no sliders.

JGood,
What size aluminum angle is that?

[kishg]

I would recommend using Lee's side mounts, I have them myself. However, I'd recommend using them in conjunction with angle iron/aluminum to mount them to the floor and bypass the factory sliders.

agree. no sliders..

[JGood]

haha. I'm guessing you were late to the game, and were posting same time as Lee. See the post above yours.....

That's definately the cleanest setup. And in all honesty-probably one of the cheapest when all is said and done.
