Hundreds Of Products Ready Today. Dispatch/Collection MK RX5 bucket seat guide
All years
In a seven-style car like the RX5, space is the constraint and the rear bulkhead is what a seat is fighting. The Cobra Roadster 7 range and the Tillett B6/B8 shells are both built for this style of cockpit generally, not this car specifically, so they suit the RX5 well.
We do not currently stock a harness confirmed for the MK RX5. The options below are built for the Westfield, a different kit car manufacturer with its own chassis design. Confirm with us before ordering.
- The Cobra Roadster 7 range is a narrow-fit shell shaped for seven-style cars generally, including the RX5
- The Tillett B6 and B8 shells carry no car-specific claim and suit this style of cockpit
- We do not stock a harness confirmed for the MK RX5. The listed options are built for the Westfield, a different manufacturer, confirm fitment with us first
- Harness slot seats in this range are 4-point compatible
- Harnesses above 3-point need a roll cage or a properly engineered harness bar

Common questions
Will a Westfield harness fit my MK RX5?
Not confirmed. MK and Westfield are separate manufacturers with their own chassis designs, so send us your anchor point dimensions before ordering rather than assuming a fit.
Do the Cobra and Tillett seats need a car-specific mount?
No, both are built generically for seven-style cars including the RX5, not this car specifically.
Can I run a 4-point harness without a roll cage?
Usually yes if the anchor points are the standard seat belt mounting points, but check your specific build. A 6-point harness always needs a roll cage or a properly engineered harness bar.
Which seat should I choose if I am fitting a harness?
The Sport Turbo versions have harness slots built in, which saves adding them yourself.
