1993 Modifications
Steering column lowered with a pair of spacer bushes fitted, you must loosen the rack to take any strain off.

Rear brakes were stripped and back plates removed the a series of holes drilled to vent the brake dust out, also four 13mm holes were drilled in the brake drums face, this had two benefit's that the brake dust from the linings would be self extracting and also a flow of air could get round the shoes.

The brakes worked well but had a lack of feel, so the brake pedal leverage ratio had to be altered, which meant that the length of the arm that was welded on the top of the pedal was shortened, to increase power on the pedal and increase the movement of the pedal..

The engine was running well and at the end of season a visit to George Bevan to check my engine which passed as built right phew! all those years of being covered in oil since the age of 12 have paid off.
George fitted a few extras such as adjustable oil pressure relief valve running set at 80 PSI at 3000 RPM cold with R40 and my sump pan and pickup being extended downwards to combat oil surge, also a change in jetting he's the Boss and won many Championships and I haven't yet.

1995 Modifications
The front discs were replaced with larger ones which came from set of wishbones I had bought from a space framed car so I don't know what they were from but they bolted straight onto the hubs MG I think, the calliper brackets had to be remade to move the calliper further out due to increase diameter, first track test proved that the fronts were locking up first, so the brake bias was wound off and the overall result was a more progressive feel to them.

Temperature on hot days was a little high hitting 90/95 sometimes so the floor in the front behind the radiator was cut out more to the same size as the radiator, a chat with George at Brands revealed that my plumbing of the header tank and the type was not up to task, so the football type tank fitted was replaced with a proper swirl tank I designed to fit, and Autocross made up for a reasonable cost. Also a header tank fitted above to keep the system topped up, in the event of a leak the system keep topped up buying some time and the chance of finishing the race, as the saying goes to finish first first you must finish..

Testing at Goodwood I tried running the Webers without the K&N filter's to see if these restricted the airflow and slowed the car, this made no noticeable deference and lap times remained the same.
Back on they went I would rather my engine lasted longer, these are better than the foam type which still let in fine dust which I have seen on the inlet trumpets when stripping engines that run this type.

The steel doors were to be replaced with a fibreglass pair I had bought but these were so tatty I ended making up my own, the weight deference is vast but when you then fit in some door bars to the cage for protection a the weight goes back in!
The windows had all the glass removed and perspex fitted.
On the subject of weight.

1997 Modifications
Martin of MH Tools made up some solid bushes to replace the rally ones fitted in the suspension arms this gave the car a little more feel but did not make it any faster! looking at the stop watches.

The rear brakes were replaced by discs as I prefer to be over braked, this entailed having to make up some mounts for the viva callipers and weld these onto the bearing carriers on the suspension arms, also Martin modified the discs to fit.
These first time out testing at Mallory park was a bit lively as the back was so over braked it locked up to easily this made the car wave all over the place going into the hairpin, I adjusted the bias fully to the rear which sorted the problem but left no room for adjustment.
Later on I replaced the .625 master for the front with .75 which brought the brakes back into balance on the adjuster.
The fitting of rear disc brakes is not essential as I have seen cars winning with drums on the rear its really whatever you like.
With today's short race's of 12 to 15 laps drums front and rear would still work well as they would not really get long enough to wear and the peddle to go long.
The tyres had to be changed to Dunlop 4.50 M 13 so I dropped the rim width down to 5.5 x 13 Weller 8 spokes

1999 Modifications
Battery moved from the original position to inside the car, in a sealed box as it is a lead acid type, I have seen way to many people have problems with the dry cell type. A few kilos more weight for reliability is well worth the trade.

2002 Modifications
Made up a cold airbox so that the air is taken from the holes on the top of the boot lid.
Also as a bonus for winning the Championship I replaced the Steel Weller 8 spoke 5.5 x 13 wheels with a new set of 6x13 Compomotive Minilites to give the tyres a little more support and save weight, as it turned out the steel 5.5 Inch V's alloy 6.0 Inch weighed the same.

2004 Modifications
Got an new large capacity fuel tank made up for endurance events, trouble is its adding weight!
