The change in design are the two hardened steel dowels in the outer washer and the slots in the outer plate which guide the pivot pin in the correct horizontal alignment.
New For August 2023 MK3 Vesion. I have changed the design slightly from the dowel pins to M4 SS Counter sunk screws . This eliminates any issues of the dowel pins coming loose and falling out.

NOTE IF you are using a galvanised subframe you will more than likely need this kit as the process of hot dip galvanising (molten zinc) involves temperatures of around 450degC this is sufficient to distort a welded assembly such as a subframe which unless checked on a jig afterwards and corrected then I can guarantee they will be distortion.

This kit was designed and developed by Mike Satur to allow the adjustment of the camber both front and rear of the car by allowing the top pivot to be moved inboard. The MGF front and rear and the TF front design does not allow the camber to be adjusted. This has always been a bone of contention and a lot of the cars from first production had issues with inner tyres scrubbing and were recalled for 'adjustment' and new tyres fitted under warranty, if you want your car to handle correctly. The manufacturing tolerance of the subframes on many cars can be wildly out and invaribly the camber is out because of this. These kits will correct this anomaly and allow 6-8 mm of adjustment of the top arm .This is sufficient for all road cars and the majority of track cars.
Sold as a kit for either front or rear, order two kits if you want to adjust front and rear camber on your MGF or 1 kit if you have a MGTF as the rear has adjustable lower arms to allow this.
It is fitted by removing the top arm pivot bolt and modifying the rear hole in the subframe to allow the pivot bolt to slide inwards to adjust the camber.The front hole has a two washer design to replace the single one that allows movement in a pre-formed slot and the outer clamping plate to slide guided by two M4 screws and then clamped by the two 6mm existing screws. Once the adjustment is made the two 1/2"UNF pivot nuts (New ones supplied in the kit) can be tightened to maintain the correct adjustment. 
The washers and locating plates are all made from stainless steel so will stay in top condition for the life of the car.
This kit is sold as an axle set so if you require adjustment to both front and rear please order TWO kits. Note the TF rear  has adjustable lower links and a different design top arm.If you have the solid lower links then I advise to use this kit to adjust the camber.
NB: To fit to the front subframe the rear pivot bolt hole is obscured and we recommend that the subframe is lowered to allow this, the rear subframe can be left in position as access can be gained from the rear.
I advise to change the pivots to the new stainless steel type with the revised oilite bearings. This will add £40 to the cost per kit.(You will receive 2 pivots and 4 Oilite bearings,inner O ring seals and outer seals 2x M6 grub screws to blank of the redundant grease nipples and a bearing removal disc per camber kit.) SELECT OPTION REQUIRED. Note once the oilite bushes have been inserted they may require reaming to the correct bore diameters for the 3/4" dia shafts.
It is advisable to fit the subframe crash tubes we manufacture as this allows access to the adjustment pivot without having to remove the bumper and stock crash cans.
The car must be on sliding wheel turntables as used when adjusting the alignment and this may vary between different wheel alignment companies. Access is easier whilst on a 4 poster ramp. Corner weighting is also adviseable when used in conjunction with the Transformer or FCCKit.
If you haven't reasonable engineering skills then leave this to someone that has the equipment and technical knowledge to be able to fit the kit and adjust the geometry correctly, otherwise you'll think this is a bit of a 'faff' (unquote) but until some bright spark can come up with a more cost effective way of adjusting the camber this is currently the best option. Please do not swap any bolts/fixings for alternative parts they have been chosen for a reason..also do not use impact guns for assembly.
An origional design from Mike Satur.
Due to the economic climate the cost of manufacturing this product continues to fluctuate  All the plates and washers are made from stainless steel for long life and reduce the possability of the parts seizing during their service.
