How to improve the MGB GT 's suspension

"As engine and braking performance improve it becomes more and more essential that the car's roadholding is also correspondingly improved." Here are some modifications for front & rear suspension which will find their way into my GT...

Front Suspension

In addition to the standard modifications (3/4" roll bar, Super-Flex polyurethane bushes), a coil-over-telescopic-shocks conversion for the front suspension will replace the standard lever arm damper and spring unit. On coil-over-shocks suspensions, the damper is acting in the same plane as the spring, making it much more effective.

Other suspension modification kits for the MGB use also telescopic shocks, but with spacers etc. to fit them alongside the spring, some with the old ARMSTRONG lever dampers still in place (minus their valves). In my opinion, the coil-over-shock system is the only useful alternative to the original front suspension.

There are some conversion kits on the market: MOSS, MGOC, NG Cars (just don't look at the cars of the later) and Ron Hopkinson and maybe more. I will go for the MOSS kit, because it has the neatest layout and requires no or very few modifications to the front crossmember. This enables me to convert my car back to original specification. All restoration and conversion work will be featured on these pages. Work has already started, so please visit again...

Rear Suspension

MOSS coil-over-shock kit
this seems to be the best layout
  •   Bushings & Shock Absorbers

  • The rear axle will see just a few modifications: Super-Flex Polyurethane bushes and a telescopic damper conversion for improved handling. I chose KONI Classic shock absorbers for their quality, looks and maximum ground clearance.

  •   Standard Leaf Springs
  • If you stay with the original leaf springs, the best way improve those will be to install the triangulation kit offered by the MGOC. This kit bolts directly on the springs and reduces spring wind-up.

  •   Composite Leaf Springs

  • I also love the idea of fitting a composite leaf spring (from British Automotive or MGOC). Their biggest advantage is the reduction of unsprung weight of approximately 10-15 kg! The composite material responds also much quicker than a steel spring, so telescopic dampers are a must. Apart from being extremly expensive, these composite springs might seem a bit too "new" and high-tech for a classic car, so...

  •   Parabolic Springs

  • ... I choose parabolic springs, offered by the MGOC (about € 300). These have a parabolic (as you might have already guessed...) taper rolled into it, making the spring thickest in the centre and tapering evenly to the thinnest part at both ends. This will allow progressive flexing from lesser road impacts whilst retaining the max load bearing capability. Also, the unsprung weight is reduced, all together resulting in an improved ride comfort and better roadholding.

    Parabolic springs have no interleaf friction as standard leaf springs, so the use of telescopic shocks is necessary.
    What I don't like on the MGOC kit are the shims for setting the height of the car, those are looking like an unprofessional DIY setup, and are also prone to corrosion. After leveling the hight on my car, I will replace them with specially machined and powder-coated blocks. Sexy, isn't it?

    After testing my modified GT on the road I'll see if there is any need to install a bolt-on Panhard rod...

    Not good: Shims for leveling lateral hight, as shown on this MGOC car, will be replaced with machined blocks on my GT
