Competition seats for the MX-5 Mk3Which bucket seat for an MX-5 Mk3 (NC)
The OMP TRS-E Velour at £239.40 is the practical FIA-rated starting point for a track day car. If you want a lighter fibreglass shell, the Sparco Grid Q at £438.00 is well judged for the money. For an NC built properly for competition, the Sparco Circuit QRT at £528.00 gives the strongest support here.
Roll bars and cage
Cybul make separate rollbars for the two roof types: the Soft Top Version at £659, and the PRHT Version at £659, or in stainless steel at £1,138.80. The Custom Cages Multipoint T45 kit at £1,818.30 is the full FIA/MSUK compliant option for a car built properly for competition.
💬
Roll protection for the MX-5 Mk3Which roll bar for an MX-5 Mk3 (NC)
Check whether your NC has the soft top or the PRHT power retractable hard top before ordering, the two roof mechanisms need different Cybul rollbars, both at £659, or the PRHT in stainless steel at £1,138.80 for a longer-lasting finish. If you are building for competition rather than adding a harness bar, the Custom Cages Multipoint T45 kit at £1,818.30 is the step up.
Harnesses
Harnesses need a roll cage or harness barA 4-point harness with separate shoulder straps needs proper attachment points above and behind the seat. Fit a roll bar, roll cage, or a properly engineered harness bar before using anything above a 3-point belt.
The TRS Clubman 4-point clip-in at £120.00 and the Sparco 4 Point bolt-in at £97.20 are the accessible options. The OMP 801 FIA 4 Point at £181.44 and Sparco 4 Point Club Racer at £214.20 sit a step up, with the TRS Magnum 4-point FIA at £246.00 the premium choice.

Common questions
How do I know if I have the soft top or PRHT?
The PRHT is a power retractable hard top, a folding metal roof rather than fabric. If you are not sure, check whether your roof is metal or fabric when folded, or send us the registration.
Can I use the soft top rollbar on a PRHT car?
No. The roof mechanisms differ and Cybul build a separate rollbar for each. Confirm your roof type before ordering.
Do I need the full Custom Cages kit or is a rollbar enough?
A rollbar gives harness bar mounting without a full cage build. The Custom Cages Multipoint T45 kit is the step up for a car built properly for competition.
Can I run a 4-point harness without a roll bar?
No. A 4-point harness with separate shoulder straps needs anchor points above and behind the seat. Fit a roll bar, roll cage, or a properly engineered harness bar first.
More help
Confirm your NC’s roof type before ordering a rollbar. Cameron works through the seat, mount and car combination together.
