Wondering the same!

And the URAS steering spacers are available from rhdjapan.com i believe....

I would love a quicker rack but since my cars still in pieces, i'm more concerned with bump steer and roll center corrections....

I wish T3 would step it up and show us some more love!!!

Spacers are not an option for anything but a drift car.
They move the inner rod-end swivel point outwards which will increase bump-steer.

Actually it depends on the setup. Some cars suffering from bump steer can near zero it with spacers and shims. I need to go measure but the 185 arm pivot point may not be in a well designed are in consideration of lowering the cars. This is why I ordered a bump steer gauge. This is a subject too many have been guessing at, including myself, and I think this is an issue that could be what is holding back the 185/165 platforms from being competitive on an low buck builds.

Edit on a related note I think the easiest solution is buy a steering quickener and have you oem rack Modified. This will help avoid too much pivot change when using other racks. These pivot changes may help in some instances but you have to do your math first and figure that out beforehand.

Bump steer isnt that important compared to a lot of other suspension geometry specs.
Ive made massive front end grip improvements without even looking at what my bumpsteer is like.

I think ive found a full Toyota 86 (Scion GT86 or whatever you want to call it) steering setup for sale for a very reasonable price.
If the rack is in good shape, ill try to use it in my 185, along with the steering column and EPS stuff.

Care to elaborate on what you did to help improve front grip? Just want to compare it to what I've found works for me, maybe we can both find some more time!

Lots of caster and good suspension are the main things.
Not going to go into it anymore here, its OT and have done so in other threads.
