44-Year-old Cobra Wins Street Car Challenge

[Cobra #3170]

You are very observant D-CEL, the rotor is so close to the steering arm that I had to radius the inboard face of the rotor along the outer circumference.
I had to repackage the whole deal with the 13" rotors to make it work. I have a reverse hat that moves the rotor as far out as I can and still have adequate clearance from caliper to the wheel inner face. I cheated by reducing rotor thickness .125 to 1 1/8 and moving the wheel outboard .125. I still have my Ackerman with the new set up and don't have the outer tie rod on top of the rotor. I have 1" bore F and 7/8" bore R AP masters with a mechanical bias adjuster that works well with the current calipers, I'll have to see how it is with the new design, efforts have not been bad with the old set up.

I could not drive this car without Power steering now. You should really give it some thought, sometimes the car can do things that you would not believe, if only you could move the wheel fast enough. I also installed a smaller Momo wheel for hand clearance at the door, this really requires PS because of the reduced leverage.

My amateur racing experience is in Formula Atlantic cars so I am really spoiled in terms of steering and brake response this has driven me to try and improve those two areas over the years .

With that kind of turn in I would have thought it would be a little twitchy , must be amazing to drive, It’s hard (for me) to imagine a Cobra you don’t have to wrestle with.
Wow 10 years! I think new package would yield some big improvements.
That steering arm looks…problematic for a big rotor swap. Is it just an optical illusion or is it really in the way?
Thank you, I’m happy with them. I’m still messing with the M/C’s, F/R bias and pedal ratio. I think they require a little more effort than they should.


Craig,

Yea well NO... LOL
When I was putting it together it up, a friend stopped by to hang out "I’m a pro at lock wire! I can do that"
So I said "Great!!" and moved on..
I was also building my master cylinder/balance bar assembly at the same time and it was giving me fits (not knowing the factory had the pedal ratio at 3.5-1!!)
So a couple of days later, in the midst of staring blankly at the car up on jack stands with the wheels off, I said "DOOOUUUUGHH!!!" lol
