Be careful what you do with your TR7 steering. The most dangerous thing about my Honda S2000 is the too light, too quick steering.
When I was a young bloke, racing Formula 1 & Formula 2 open wheelers, & had a steering suspension & brake shop. I did a fair bit of suspension tuning for other people. There were quite a few open wheelers with a local rack, with 1.5 turns, lock to lock. This gave go-cart like steering, something you don't want at high speed.
I did suspension set up on a number of these, & the first thing I did was throw out the rack, & fit a new rack & pinion, with 2.4 turns lock to lock. In a couple of instances this was all I did along with an alignment as the spring rates & shock settings were fine.
In each instance the driver was a couple of seconds quicker, as he could now add fine inputs to the steering, rather than the ham fisted inputs the fast rack caused.
An over fast rack is fine on really tight stuff, but has no place in a car that is going to be cornering at 80 MPH & above. In fact I believe it is the over quick steering that is responsible for most S2000s that die, do so backwards into the scenery, after an over correction of a minor slide.
I believe these over fast racks are used so modern ladies can turn right-angle turns in suburbia, one handed, while still texting with the other.
