Yes I am sure. These wheels are -19 et 9.5 inch wide and the other option would be the -13 et 9 inch wide wheels with a small spacer. The current wheels really want a wider tyre which will overpower the arches in my view

reading about crank pressure blowback.... ie that happens more than actual draining.....

Yeah it's more to stabilise pressures than for oil drainage believe it or not. That coupled with a decent catch can setup should be fine. I'm not sure which one I'm going for. I do like the Franklin engineering one and the Ross performance one.

Really nice job you’re doing here and the car looks really solid! Interesting that the STI rack is a possibility, will add that to the list of potentials. Is it a similar ratio to the S30 rack?

There are different lock to ratios available, I've gone with a JDM only 2.2 lock to lock witch might be too much, these are harder to get. The 2.6 or 2.75 are cheaper and fitted to UK STI's they are close to stock S30. The US cars had a "slower" rack than UK ones

just think about trying to park an S30...

I presume the rack is all coming apart again otherwise you have forgotten to fit the rack bellows and track rod locknuts.

As has been documented on another thread, I have built a similar p/s setup using a 1999 Subaru Forester rack which I think was a 2.75. The early WRX racks are also compatible with the right adaptations to the track rods.

yes, it's all coming apart again :)

2.75 is close to US standard rack ratio for an 280Z and should be fine. I hope mine is not twitchy on the road but I had to try, I can resell with no issues as the 2.2 are so rare now in the UK
