OEM seat vs Bucket seat weight loss

[razorlab]

I was taking my seats out for a rollbar install and decided to do some weighing to see how much a proper bucket seat saves us.

• OEM Drivers seat: 55.4lbs
• Sparco Evo with Brey-Krause side mounts, Brey-Krause six point bar (attaches to BK Side mounts), OEM belt buckle, and Schroth six point harness: 29.4lbs
• Macht Schnell floor mounts, didn't take them out but shipping weight tells me they are around 3.5lbs
• Total weight savings: 22.5lbs

Obviously you would save more weight without the six point harness and proper underseat mount but what's the point.

Did you happen to take more pics on this?

Does that give any head clearance compared to stock setup?

Great question! And less head jacked forward like the stock seats?

Yes it can be much lower than oem. Yes it gets rid of the “head jacking”

Real race seats are designed for the helmet. Head position is so much better. I am 6,2” and my seat is in a low hole on the rails. I still have broom stick room above helmet

recently removed head liner so even top mount air connection should work now

I’m 6.6” and I have loads of room left with a helmet.
My seat is as low as it can be .

Thank you for the replies, I am 6'4" on stock seats and looking to get some seats next after fixing a couple issues the track brought out in my car.

Off topic what issues?

Off topic what issues?

I've been having a diff issue where under load on fast corners where the track can have some bumps and inconsistencies the car would go into limp mode with a diff code, I could mediate it with turning off all the traction controls and shifting manually. On hot days I would have overheating issues and my brake pedals would fade around the second hard lap and I would loose half the pedal. The biggest was I was chunking the outside front tires quiet a bit. I was running a stock car this past season so just invested some cash into coilovers and square setup etc and changing some things around to deal with all that.

** diff is pretty stout and on point. Have only had a diff limp error once when I was really skidding around too much. Diff cooling plate, check/chnge fluid

On hot days I would have overheating

*** in the south stock set up will pull timing and power on the hot days. Upgraded manifold is only answer. Never had a true over heat.

issues and my brake pedals would fade around the second hard lap and I would loose half the pedal.

**** absolutely have to upgrade fluid and pads if you track even at novice level.

***** add camber. Check pressure make sure side wall is not rolling over

Ditto what Rock said. Drive in manual mode, turn the traction control garbage off, buy track pads, change your DOT4 brake fluid often. You can keep the stock springs or get coilovers. Sound like you’re on the right track!

Sorry for the late reply, so update after having a couple track sessions on new setup. I run all aids off and manual, UMC has been cold lately with one day being rescheduled due to snow. So far the car is a new animal. I am currently running around -3.5 camber on front but the wear on the outside of my tread of my tires is making me suspect I do not have enough currently for the tighter layout of the track. Changing to dtc pads and new fluid was a life send so far on my brakes but when it warms up is when i really want to concentrate on how they feel.
