GC Fabrications GCR3 Roll Bar For Mazda MX-5 NA NB

22 users have this item in wishlist

This listing is for a GCR3 (X Brace) bar compatible with both Hardtops and Glass Screen Rear window soft tops. Plastics will fit but require a push to get down.

Note; These units are generally built to order and can take 2-4 weeks for delivery – trust us, it’s worth the wait.

The GCR series of  roll bars are designed with safety and strength in mind, to do this some compromises have to be made with respect to seat movement – however, our testing has shown a driver of 6ft can find a suitable seating position, a bucket seat also helps massively.

Gcfabrications roll bars are not just a safety device they also aid chassis rigidity and improve handling.

This product is manufactured from MSA specified CDS tube and welded by fully qualified welder fabricators. Our roll bars are zinc primed and comes with a durable satin black powder coat finish.

BOFI Racing Highly Recommend the GCR range of rollbars and run them on our 3 ‘BOFI Spec Cars’ – These Rollbars are one of the largest you can install as a bolt-in bar, using all available space with minimal intrusion into the cabin. They are strong, well made and frankly we’re not sure how you could improve further. They also serve as a perfect base to bolt door bars to, which GCFab also create, we’ve tested and absolutely love them.

They work with hardtops, soft tops, standard and bucket seats and do allow you to maintain the standard seatbelt – perfection.

Features Include:

Manufactured from high-quality cold drawn seamless tube.
The cross bracing improves driver protection without impeding rear visibility, including the X brace.
Designed to work with soft tops and compatible with glass and plastic rear windows.
Suitable for use with hard tops
The GCR also comes with built-in harness bar which allows full seat movement.
This product also comes with a high tensile fixing kit complete with sandwich plates.

Fits all RHD and LHD Mk1, Mk2 & 2.5 models

    Bought this roll bar for my mk1, received it exactly a week later. The box was a bit damaged when it arrived but the bar itself was perfect as it had been wrapped in foam and bubble wrap. The bar is amazing quality, feels very well made and I can’t wait to get it installed!

    Bofi were incredibly helpful in answering any questions I had about when I’d recieve it, and were able to clarify further details I wanted to know about the roll bar. The person I spoke to on the phone showed genuine interest and enthusiasm for their products and MX5’s. I couldn’t have asked for an easier, quicker and more perfect experience, Bofi have definitely earned themselves another loyal customer.

    I’m located in Detroit, Michigan, USA. From time of purchase to delivery, it took 9 business days. Very impressive for a delivery overseas amid the COVID-19 virus. Bar arrives with great packaging. Has foam wrapped around the entire bar, and the hardware/brackets was very securely taped to the mounting feet.
    Price was great too. A brand new bar from harddog would have cost me $150 more and still would have lacked the harness bar. (If ordering from USA, be sure to use a credit card that doesn’t charge a 3% foreign transaction fee).
    I’m fairly novice working on cars, but the process was pretty straight forward. Took me ~10 hours over 2 days. Bar fits great in the car and everything lined up perfectly. Requires some trimming and bracket removal, but to be expected.
    Overall couldn’t be happier with the results. I would highly recommend.

    My GCR3 roll bar arrived today in just under 2 weeks despite the 2-4 weeks lead time. Box arrived mildly damaged due to courier however GC Fab wrapped it properly and the product is in great shape and fantastic quality.

    Definitely not a lightweight product, which isn’t a problem at all as this is one of few areas I wouldn’t want to shed weight.
