What should be my first course of action?
I think your first course of action should be to learn that an officer can testify to citing you for an alleged speed based upon a "visual estimation" of that speed. They are trained to do so and their testimony to such is recognized by courts in California and has been used to convict many drivers of speeding citations.
However, I don't know if he can cite you for a 22405 by only stating a "55 to 65mph" range like that. CVC Section 22405 goes as follows:
22405(a) No person shall drive a vehicle on any bridge, elevated structure, tube, or tunnel constituting a part of a highway, at a speed which is greater than the maximum speed which can be maintained with safety to such structure.
But, if you look at22405(b) Upon the trial of any person charged with a violation of this section with respect to a sign erected under Section 22404, proof of the determination of the maximum speed by the Department of Transportation or local authority and the erection and maintenance of the speed signs shall constitute prima facie evidence of the maximum speed which can be maintained with safety to the bridge, elevated structure, tube, or tunnel.
... it states that a sign must be erected indicating a maximum speed which must also be justified by what I can assume is a Traffic and Engineering Survey. So again, I can assume that he would have to cite you for a particular speed; not a range of speeds. I have not seen that many 22405's so I could be wrong.
Second, and at least to convince yourself that you are not guilty, you need to revise (in your head) the statements that you made in your first post. For example, you stated:

I do not believe that I broke traction at all
But then, you listed a bunch of reasons trying to justify why you broke traction:

Batou
I wasn't trying to "drift" or anything.
Which does not prove that you didn't break traction. In fact, it may suggest that you did break traction even though you weren't trying to "drift or anything"...

My tires are quite old,
Which might suggest that you did break traction...

and do squeak if I go over the bumps on the road,
Pretty creative, but it might also mean that they "squeaked" because you broke traction...

or touch the paint on the side of the road.
That one made me LOL...

I believe this is what the officer heard (I had the radio on, so I didn't hear anything).
One might also believe that he did hear a squeak, or a screech which led him to believe that you did break traction. So he looks over, sees your car, which is lowered, sees a roll bar, and also sees that you are driving (by your own admission) faster than traffic around you...
How many red flags do you expect to hold up before he decides to pull you over!

My vehicle is also lowered, has an aftermarket steering wheel, bucket seat, and roll bar; which leads me to believe that he pulled me over because of this.
Add that to the fact that you are 21, and assuming that the officer testifies to seeing those modifications, or in the slight chance that you might bring them up like you did here claiming that he "profiled" you, do you think this will work in your favor (especially the roll bar) or do you think it will help the officer's case in proving that you may have been speeding or do you think the Judge will hear that and assume that the officer picked on you unfairly?

He stated that I would be getting a ticket for "exhibition of speed, and might get arrested and/or have my license revoked, but from everything I've read so far, this violation code doesn't seem to indicate anything like that.
What have you read so far?
By the way, he forgot to tell you that you car will be impounded.... And had he done any of that, and assuming he testifies to the events as you described them here, do you think the judge will believe you or the officer?
Back to 22405(b). Was there a sign posting a speed limit on that on ramp? If so what was the limit?
Also, you might benefit in trying to obtain a copy of the Traffic and Engineering Survey for that on-ramp. You can contact CalTrans to see if you can get one through there but you should also be receiving one as part of an Informal Discovery Request that you might file and serve. Google "Informal Discovery Request" to find out more. That request should also provide you with the officer's copy of the citation and on it, you might find notes that he made detailing what he saw and why he made such determinations as he did.
