All rubber hoses replaced by braided items.
No aluminium components or extra cooling ducts. A quick shift, updated clutch, and extra lower stabiliser bar completes the package. Also a central oil pickup is permitted along with a strengthened lay shaft. Original ratios to be maintained inc differential, but the latter may be upgraded to a stronger cross pin example. The ECU must be sent away to be independently tested and sealed. Also a top steady bar between thermostat housing and bulkhead. Three branch exhaust manifold and an RC40 or Maniflow exhaust system restricted to 1 7/8”. Updated radiator using the original mounting points, small additional in line cooler and an oil cooler within the confines of the engine bay. The original 1275cc capacity must be retained. Head work limited here to a light skim of the head, and double valve springs. 6.5mm spacers and longer studs at the rear only. Tie rods and track rod ends are upgraded also. The bushes will all be replaced and updated where permitted and the inherent standard Mini ‘positive’ camber is adjusted to the more track friendly ‘negative’ variety by using longer lower front arms and adjustable outer rear attachment points. The bump stops can be replaced by shortened versions or cut down originals.
#Might mini circuit racer series
To accommodate the lower ride height the shock absorbers have to be replaced also and for this series they are specified as lowered GAZ adjustables. However the ride height is reduced from standard using reduced length and adjustable ‘trumpets’. These dry out and become more rigid over time so they should be replaced. The suspension maintains the original design rubber cones. However we plan to fit a racing tank with foam baffle and internal filler still within the boot area. The original tank can be retained but the filler must be flush mounted. The battery will be replaced by a sealed racing version. The battery cable from the rear mounted battery may be run internally rather than in its usual channel under the floor as can the brake and fuel pipes. The battery isolator must stop the engine and have an exterior mounted activation just like the extinguisher. Extra gauges, switches, and a battery cut out can be mounted separately in the area just to the left of this.
The dashboard is removed but the instrument cluster remains in situ. You plumb in a fire extinguisher system with remote pull and bolt in a racing seat.
#Might mini circuit racer windows
The rear and side windows are replaced with polycarbonate equivalents and the fog lamp moved to the centre of the rear window. It will then be sent to be sprayed inside and out. This should be all the protection needed for many years to come. This is the same technique used by modern manufacturers and a company called SPL have been doing it since the 90s. The body will then be sent back to the dippers for a final dip and totally sealed with a modern epoxy coating. Once that’s done we’ll inspect it thoroughly, finalise the repairs and weld in the extra mounting points required by the regulations for the cage, subframe, and seat mounts. Stripping also saves a small amount of weight. I’ve seen minis that have had sills filled with body filler instead of being replaced! It’s lazy but can usually be spotted using a small magnet when looking for a prospective donor. We will get it acid dipped to remove all the seam sealer and noise material as we don’t want there to be any surprises for structural integrity and any previous repairs will be unearthed. You take an SPi Cooper (without a sunroof) repair all the rust, gut the interior and strip everything back to the bare shell. I’ll only highlight the main points here. The regulations are published on the Mighty Minis website and are considerable in length. (BELOW IS ALSO COPIED TO THE TECHNICAL SECTION) All safe in the knowledge that it hasn’t been thrashed to within an inch of its life. We can tailor it to our own specification in terms of extra instrumentation and data logging. But where’s the fun in that! ? We’d only be tempted to rebuild it anyway, adding to the cost.īy building our own car we have the advantage of knowing it inside and out.
This would probably be more cost effective and we’d be sure to meet the regulations with a car that’s already passed inspection. The racing is close and the championship is often undecided until the last round.Ĭomplete cars sometimes come up for sale with prices in the region of £6500 (at 2018 prices). The series has essentially remained unchanged since that time and as a result there’s a huge following often resulting in massive grids. This championship was introduced in the 1990s and used the current, at that time, Rover Cooper SPi as the starting point.
