Racetech managing director David Black with the seats the company makes for a range of leading car makers.

Less than three years after fire destroyed their Wellington factory, Racetech has won deals to supply its premier racing seats to Aston Martin Racing, McLaren GT and Porsche Motor Sport.

It's a huge coup for the small privately owned company which reopened at new premises in Seaview a year after losing everything in the August 2013 fire in nearby Petone.

"To be supplying seats to three of the most prestigious racing brands in the world is not a bad place to be. We have at times supplied BMW Motorsport as well. We haven't quite got into Ferrari yet, but we are working on it," managing director David Black says.

Racetech's range of motorsports seats are painstakingly hand made in the Seaview factory from either carbon fibre or fibreglass and are designed to fit different sized drivers in different categories.

Seats range from $500 for an entry level model suitable for ClubSport up to $10,000 for a professional seat like those used in the V8 supercar series and in touring cars in the United States.

Black credits the company's revolutionary seat design for its success in signing deals with the big names in European motor racing.

The world class seat dates back to 2002 when Racetech was asked by Daimler-Chrysler to develop a seat for the competition coupe Dodge Viper. Their safety advisor, the late Dr John Melvin, talked to Black about mounting the seat not just at floor level but also at shoulder level, transferring the load to the chassis and enabling drivers to better survive high speed crashes.

"Really all I did was listen to what he said and follow his guidance."

Black says that while the seats are designed with safety in mind, the fixing system also helps drivers to better feel the performance of their cars.

"Because the seats are rigidly mounted to the car they can actually feel what the car is doing better. That is part of the reason that some of these big manufacturers are coming to us.

"The other reason is that because of the back mounting, it means that the floors of the cars don't have to be strengthened or modified because most of the lateral load is taken out at shoulder level."

The top performance seats have other features too, like air cooling, a bonus for drivers competing in endurance series or in hot climates.

Black gets a huge kick out of seeing the world's top drivers using Racetech seats.

"It is fantastic. But the other side of it is I get really frustrated when I see drivers getting killed when they don't need to. If they had adopted our seats or the latest FIA standard earlier, then maybe they would still be with us."

Racetech was asked by the FIA to work on a safer seat for rally cars in 2003 after British drivers Mark Lovell and Roger Freeman were killed in a North American rally accident. The seat Racetech developed was adopted by the Subaru World Rally Team in 2008 and helped save the lives of Chris Atkinson and Stephane Prevot when they were involved in a crash at the Wales Rally GB.

Black, a former national rally champion, knows all too personally what a high impact crash feels like. In 1994 he 'flew' his F2 rally car over a 75 foot (23 metre) cliff, experiencing a 'severe frontal impact' first hand.

He makes a point of being present whenever Racetech seats are put through crash testing and says many top race teams still fail to understand what happens to a driver in a serious crash.

"The testing for the latest standard is done in Milan and it is a quasi-static test so it is just loads being pushed on the seat and the seats are only allowed to deflect so far, but it still gives you an idea of the sort of loads that are happening in a race car.

"I weigh roughly 100 kgs so if I hit a wall at 100 g then that is 10 tonnes being pushed onto the seat. People just don't understand that that much load could be exerted by the human body."

Black hopes the deals with Europe's top racing teams will open new business opportunities.

"It will hopefully open doors for us to move into other more mainstream manufacturing such as seat manufacturing for sports cars."

For now though, their seats are available off the shelf at the Seaview showroom. You can even get your name on it.
