Racetech race seats are regarded by many in the driving seat as the best in the world. Our composite and carbon fibre race seats are fitted to thousands of race cars, touring cars, rally cars, drift, drag and speedway cars. We keep people racing fast, safe – and we do it in ways that break the mould for safety, comfort and performance.

 From our HQ in Wellington, New Zealand, we design, test, manufacture and sell our comprehensive range of race seats, alongside other top-class race products, to iconic racing marques around the world.

Racetech seats and products perform. They’re comfortable; they fit perfectly, they feel secure, they connect you with your car in ways that give you the confidence to safely push your boundaries. We get that need to do better. It drives us, too—that competitiveness.

We know only too well that thing that happens when you feel the seat wrap around you. Suddenly what you see ahead of you becomes your world. That adrenalin rush and focus is addictive, calling you back week after week, race after race. It drives you to shave fractions off last week’s lap time, to out-position a rival, to throw everything you have at being as good as you can be.

No other racing seat manufacturer is more concerned about drivers. Our culture and purpose revolve around getting you and every other driver home. That determination to make sure racers get to walk away safely from their time on the track and the road plays out in every aspect of our approach. No detail is too small when it comes to saving lives.

Our commitment carries through to our insistence on quality production. The only price we put on safety is a fair one: we don’t skimp or cut corners—the best costs what it costs.

Our willingness to recognise and address issues stems from that deep Kiwi pragmatism that lets us chase excellence at the expense of tradition. We’re a practical, grounded and free-thinking team with an eye for detail and a steely determination to consistently and carefully introduce the evolutions that, over time, help make racing safer.

We literally help set the standards for keeping drivers safe globally. We are currently a member of the FIA IWG, the Industry Working Group that global body The Federation Internationale De L’Automobile (FIA) consults with. Our team is regularly sought out by national motorsport organisations to assist with improving safety standards and understanding driver safety. Here in Australia, we work closely with many V8 Supercar teams and the TA2 Australia Muscle Car Series supporting them with driver safety.

All of that means that every time you slip into a Racetech race seat, everything we know is right there with you.

We focus on designing, developing and producing the best race seats in the world. In fact, Racetech seats are used by some of the world’s leading teams and constructors, including Porsche, Aston Martin, McLaren, Chevrolet, Ford, Dodge, and Australia’s own V8 Supercars and TA2 Series cars.

 Racetech seats are robust and supportive. They’re made that way, and they are that good because we’ve made it our business to know what makes drivers tick. We combine safety, comfort and performance in seats that drivers can depend on and that represent true value for money. They are your added advantage.

Our knowledge and experience make us the world leader in racing seat science. Our patented back mounting gives you solid contact with your vehicle and improves your feel of your race car. Not only does this enhance your performance, you’re also safer racing this way. Tests have shown that if you support and maintain alignment of the head, shoulders, pelvis and thighs, drivers can withstand enormous decelerations with minimal or no injuries.

Our expert team is passionate about the tiny details of your racing machine’s seats, harnesses, and other vital components. For us, performance is about much more than just reducing weight. All Racetech seats have parallel sides for ease of fitting and driver positioning. The lack of flex in the shoulder area of our seats helps reduce fatigue and improves safety. The six-point mounting method we pioneered helps improve car handling and the ability to tune the chassis. These features, and more, literally make the difference between life and death or injury.

With a Racetech seat, you don’t have to pay top dollar to take advantage of our innovative thinking and design. Many of the features in our top-of-the-range seats carry right across our range. No matter which seat you invest in, you still get back-mounting, square shoulders and the simple, nothing-to-fail cooling system that Porsche Works and V8 Supercar drivers swear by.

And when it comes to sizing, no other racing seat manufacturer is more accommodating. We offer you the widest range, and each seat in all our ranges includes an ergonomically moulded removable base cushion and seat geometry that ensures you’re always sitting comfortably.

Choose a Racetech seat. They’re made for people like you. Drivers.

PRODUCT INFORMATION

The RT4100HR is a standard-sized fibreglass race seat equipped with head restraint wings for enhanced safety. We have focused on achieving a lightweight seat shell with optimised geometry, straddling that line between designing the seat to be wide enough in the shoulders to suit the athletic build, but narrow enough to fit in most cockpits. Our patented back-mounted technology has trickled down from the 119 and 129 Series, giving you the option of fixing the seat to the rollcage at shoulder level. Large harness guides and a removable moulded base cushion allow a range of drivers of varying heights to fit. Breathable Spacer fabric, parallel sides and pronounced thigh support round off the features of this accomplished motorsport seat.

For the taller driver, we have developed the RT4100THR which makes use of the RT4100WTHR shell but has added high-density foam to the sides up to the shoulders to bring the internal dimensions of the seat inline with a standard-width RT4100. This seat is 60mm taller than the standard size. For the larger driver, the RT4100WTHR is 60mm taller and 40mm wider and for those wanting a seat without head restraints, our RT4100 and RT4100WT complete the 4100 Series.

The 4100 Series seats use Racetech RTB2009S steel or RTB1009M aluminium side mounting brackets.

Works well. You need to drill a 3/8” hole
Appears to be well made, alignment bar slides in nicely. As stated, you need to drill a hole in the bar for the gimble bearing driver, the directions are not clear, what I did was before I take out the old gimble bearing, put an O ring on the bar close to the last step on the bar, slide the bar all the way in, then carefully slide the bar out, this marks the distance from the back of the gimble bearing to where the shaft on the outdrive bottoms out, move the O ring a 1/4” towards the stepped part of the alignment tool (this is so you won’t bottom out the alignment tool when driving the gimble bearing in) then slide the driver puck up to the O ring and use a 3/8” diameter transfer punch through the side hole in the puck to mark the bar. You need to drill a 3/8” diameter hole in the alignment bar, two V blocks, some clamps, and a drill press will make drilling much easier, after the bar is securely mounted and centered in the drill press, use a center drill, then 1/4” drill first, using plenty of oil, drill all the way through, then use the 3/8” drill, deburr both sides and you should be good to go. People complain that it doesn’t come pre-drilled, the reason is that not all out drives are the same so you have to fit it to the outdrive that you have. Fortunately, I have a machine shop at my house and have a jig setup with various drill bushings, but the method I described above should work for you. Just make sure you’re perfectly centered and secure before you start drilling.

Worked for Volvo Penta SX Gimbal Bearing
Very heavy tool, I was surprised. Pulled my bearing like it was nothing. Putting the new bearing in was a little more difficult as you have to drill a hole in the engine alignment shaft where it will work for your particular outdrive. Not hard, but it does not come pre-drilled as the required depth for each particular gimbal bearing differs by manufacturer and model. Measure your bearing placement before removal and check that it was installed correctly in the first place. The bearing should line up with the grease fitting and the o-rings on the drive shaft should end up riding in the middle of the bearing. once you have your measurement drill the hole, I used a drill press. I suppose you could use it on multiple outdrive models as long as you can drill more holes.

Great value
This kit worked perfectly on my Alpha one mercury outdrive. I saw a lot of people mention that it was a hassle to drill the hole when you better have all this alignment stuff. I threw it in use my regular drill drill guide and then the second hole was lined up. Pulling Gimble be very easy. I did have to adjust it up at an angle because my bearing was sitting in their crooked and it came out the second time I made the adjustment to the angle. I would highly recommend this.
