If you own a Mk4 or indeed a Fiat / Abarth 124 Spider, you’ve probably heard of premature rear hub bush failure.
Developed in partnership with MX5 parts, our rear hub bush kit 210 offers a long-lasting, cost-effective fix – no need to replace the entire rear hub!
With many Mk4s now out of warranty, this kit saves owners from some seriously steep repair bills – Our customers are reporting to us that they’re literally saving £2000 by installing Kit 210! Which has been engineered with varying material hardnesses to allow precise movement while keeping NVH (Noise, Vibration & Harshness) in check – so your car stays tight, responsive, and still has that sporty zing you bought it for.
Aside from the fact that these bushes are unavailable separately, Polybush material is not affected by oil, petrol or water and is extremely resistant to abrasion, our bushes retain their original state and do not suffer from compression set in the same way as rubber or cheaper injection moulded polyurethane bushes – meaning that in normal use they last up to 6 times longer and mild steel zinc plated inserts, as used on original equipment bushes, prevent galvanic corrosion and wear to mating parts.
Not suffering from compression set also means that if your MX5 isn’t your daily driver, then the bushing will not sag and deform as an OEM rubber bush would, keeping that factory fresh feel.
Making every drive feel like the first out of the showroom, adding the front suspension and even diff bushes will tighten up handling even more so – reducing tyre costs, keeping alignments in check and really giving an impressive and confidence-inspiring drive.
Not to worry, we offer a wide range of suspension bushes for all MX5s
