Good questions!

Our steering arms are shorter then the escort arms, which is why we have the .84 correction factor. In my daily I have the old version crossmember with the 2.9 lock to lock with the AE86 rack, in our Enduro racecar we have the 2.4 lock to lock V3 crossmemeber. I was expecting it to feel to fast for the street. I actually love the feel! We picked up a 2.0 lock to lock to try for the next race :) The 2.4 needs to go in my daily :)

The reason it links you to the RHD rack is because the escort is front steer where the 510 is rear. So if you put a front steer right hand drive rack in your rear steer left hand drive 510 things work out perfect.

I reached out to the guys at Kiley Clinton and they called me back! Super down to earth dudes! They said the stock replacement (economy choice) is fine for anything that isn't racing in the dirt (we have it in our enduro car). Their racks are designed for dudes going 100mph through the dirt while catching air! haha.

Don't forget to order bushings with the rack. Only the ultra heavy duty ones come with bushings for some reason.

Keep me posted on how it goes fitting it in with the 2.4 block. That's a tall boy! I still think getting a 2.2 block might make the installation a bit easier.

You can always call our text to if you have any questions. 206-913-1466 Jeff

Thanks for the feedback. After I realized the links were ALL wrong, I did wonder if that was intentional.... Of course.

That 2.4 will fit in there if I have to use a crowbar and a hood scoop or trim some (more) off the valve cover. Not going to start re-doing the engine now. The sway bar is the only wild card at this point, but that's the fun part, right?

Just for make you say it, the MSTRD870 rack will be the correct economy rack for my LHD 510 if I want an actual 2.4 ratio when all of your components are installed. Right?

Rack bushings from motorsport-tools.com. They were very responsive to my email request:

Decided to go with the 2.4/2.0 actual ratio RHD rack. MSTRD816. Always err on the side of "too sporty", as you have found, it rarely disappoints.

That's very true! Now I want to put the 2.0 in my daily....

Yes that is the right 2.4 lock to lock rack. The crossmember was made to fit the Kiley Clinton racks, with a shim on one side (included) the economy rack fits. There is a wide rack available you don't want. It's the only one that doesn't work.

We used a NASCAR style bar under the core support on our racecar. There is also a guy in California who makes a traditional bar that fits. I don't know his contact info. Soon we will have the parts available to make the NASCAR bar work.

i have now received my rack and bushings from Motorsport-tools. Rack looks great. I ordered both their poly and rubber bushings. Well the red poly ones fit the rack very well, while the rubber ones, well, not so much. The appear a bit big on the ID. Maybe when clamped in the x member they will tighten up, but I can't see using anything but the poly ones. No play needed or wanted here!

I have also received my crossmember and assorted goodies from James. As has been previously said, this stuff is serious well built goodies. Won't have a chance to do any work on this until OCtober at least, but I'm sure it will be a joy to work with.

Yeah the bushings vs rack fitment isn’t the best on some combos. I think the problem is there are lots of rack variations. I had to put a small sheet metal spacer behind the non steering side when using the stock replacement rack but with the 2.4 heavy duty rack it was a task getting both sides in.
