DoctorMX5 doesn't just want to Keep Your 5 Alive, we'd like our customers to do the same.
There is no requirement in the MSA Blue Book for a Road Going Production Car to have any roll-over protection. Section S - Springs, Hillclimbs and Drag Races Section 10.1.2 "Road-Going Series Production and Road-Going Specialist Production, K.1.6.1 or K.1.6.2 recommended." K.1.6.1 looks like the picture below.
NOTE: The Gurston Down MX5 Championship does not have a requirement for a roll bar or cage.
Here's an example of a well designed Roll Bar.
Typically Roll Bars have problems with the type of window your MX5 has. Mk1 cars have a zip-out plastic window and Mk2 cars have a glass window.
As a consequence, the roll bar needs to be different. Here's one with a plastic zip-out window.
Here's one with a glass window. As you can see the diagonal bar allows the glass window to fit flat on the rear deck.
Prices range from £250.00 to £350.00 plus VAT AND fitting.
You can privide your own roll bar, please contact us for a fitting quote.
Door Bars are designed to provide additional saftey in a side impact. In tin top cars that's all they really do. But in open cars, they add additional strength to the weakest point in the car. An MX5 flexes in the middle. The door bar creates an additional box section, higher than the floor of the car, thus strengthening the centre, reducing body flex.
Door Bars: £150.00 plus fitting
Chassis Rail can also be used to help mitigate this flex but from a structural piont of view, they provide very little benefit.
Strut and Chassis Braces can improve the way a car feels. The reduce flex in the body sheel by bracing parts that flex.
A front strut brace should be considered essential.
Front Strut Brace: £100.00 plus fitting
We also have a range of under-body braces. The one makes the rear much stiffer. It stops movement on the differential mounts and bolts the drive train frame (powerplant frame) directly to the rear subframe.
Prices: Vary according to type of brace
