Um... did you mean Infineon is for corporate weenies?

Now, let's see that hat!

Ok nice. Pretty deep BS, I was doing some rough numbers with the spindle/hub setup I was trying to use and I was coming up with about 9" BS if I wanted to target 0 scrub... That seemed pretty high, I am looking into other spindle/hub options currently. I don't think what I have is going to work out too well... Too much SAI and the hub offset is pretty big.

Maier has some aluminum spindles with steel shaft that uses big bearings. They might work for you...

Payton King has the same size wheels and long arm deal but a .25 inch more BS so he closer to zero scrub than I am but neither of us are at true zero. Still pretty low and wide though.

I gotcha. Not sure how important it is, or if having an inch or so of scrub isn't particularly a bad thing then maybe I shouldn't sweat it. I just would rather try and do the figuring out now and optimize what I can (or at least what I think is right) rather than just compromise and call it good enough

SO now I am working on just making my own spindles. This seems like the best route for me, since I can dial in exactly what I want. I found some photos of some of the Trans am spindles, I plan on using a similar design. Mono ball upper/lower joints. Ive got speedway engineering 5x5 grand national hubs and coleman sells a weld on spindle pin that I am going to start building off..

Here is the spindle I was going to steal some ideas from and build it similar to this guy.





Id like to end up in the 6 degree KPI range and zero (or less than an inch) of scrub with an 18x11.

Made a little progress. Made a motor plate and got that tacked in. I needed to set the motor where I wanted it, next I plan on building the "sub frame" for the lower control arms. I think I am getting things figured out. I know I am 7" back from where my old motor was. And I had my old motor 2-3 inches back. So I'll call it 10" set back. Unsure on the height but the engine is very low in the chassis. I think I should be ok with pan clearance, but I have already explored some options of making a pan about 1-1.5" shorter if I need.




I'll have front and rear plates, as well as a tranny mount..

You made the engine plate? LOL

If you closely interpret my posts. I said... "made a motor plate" .That could mean I made it, some kid in china made it, or in this case you cut it for me. And did the high quality programming
