Our best seller, heavy-duty frame rails to reduce longitudinal chassis flex and protect the underside. Rigid chassis allows suspension to do it’s job properly – as a result the car gets less upset by road impurities and handles better. Frame rails reinforcement is a great upgrade for every MX-5 enthusiast.
With bent edges and no side cut-outs for improved stiffness. You can see how much difference these design choices make in the simulation attached. Our frame rails are designed to be the most rigid on the market and we don’t compromise for lower manufacturing costs in our products.
– stainless steel in 2 mm thickness
– longer design to support maximum possible area
– ready for future butterfly brace installation
– including 3 brackets for brake lines
– all required fixings provided in stainless steel
– installation guide with photos included
Brake lines are kept in the original position and are held in place by the frame rails.
Compatible with all cars from 1989 until 2005 (NA – NB – NBFL). Does not obstruct the NBFL (MK2.5) Sportive factory bracing, except for one bar which needs to be either removed or need a bit of fabrication to fit. This one bar does not help much to reduce flex while the frame rails stiffen up the chassis down the middle of the car significantly.

Just finished a test drive and I’m surprised how much difference they’ve made, immediately noticeable.
I am impressed with the quality of the rails and fixings. Very simple to fit, bolted on within two hours. Can’t recommend these highly enough.
My order arrived today and I am really very impressed. Very good quality and very sturdy.
Car absorbs bumps a lot nicer now and reduces noise in the cabin. Butterfly brace next…
