Interior mods so far have been limited, except a new aluminium gear knob and a small toy Ka.

Exterior

Lowered 30mm all round using Eibach springs

I would recommend these springs if your still looking to occasionally take a full car of passengers around with no scrubbage. Low body roll, good handling. They were about double the price of the likes of Spax and GMax, but I believe they are of better quality - also Ford sell them as upgrades for the Ka anyway! I didnt get them from Ford though as they tend to be more expensive. I can easily out corner and out handle most cars out there, which makes up for the lack of power that the Ka suffers from.

15" TSW Evo Rs, with Yokohama A539 195/45 tyres.

Decent look, a bit different from the normal five spokes that everyone has, even though these Evo Rs have been around for a long time now. Yoko tyres are very sticky but with much improved wear resistance compared to the old A520s. Not so good in the wet, but not tried many others, so don't know how they compare really. 

Tarox Monza grooved and drilled discs (front) and Tarox pads

Much improved stopping performance. My Ka is a 97 model and Im not sure whether the braking has improved since mine was built, but I felt it was definetly needed. I can now brake later than many people and take advantage.

Powerflow Stainless Steel CAT back system

The main pipe is now 50mm diameter instead of the 40mm standard with a 3.5" round tailpipe. The system was built on the car (as all powerflows are) so no problem with fitting, and has a lifetime guarantee. Nice sound, not too loud nor quiet. Breathes much more easily now, and a slight power increase was probably gained along with the Green Induction Kit.

Ford Ka Spoiler

This was fitted when we bought the car, but adds a lot to the overall look, and for the cost is well worth having. I don't like many Ka's without one now!
