Anyone have a sickspeed shift knob? looking for info..

[brzstiz]

Hey guys,
i'm looking for more info/pics on sickspeed shift knobs.
i was specifically looking at these parts:

Item #:GRN GLOW KNOB 12X1.25
Item #:BLK RLO-2

Here are the web links:
https://www.sickspeed.com/product/de...p75032-c697957
https://www.sickspeed.com/product/de...p74577-c683590

Just curious if anyone has used these shift knobs and how they fit with regards to the reverse lock-out, or how the adapter works?
anyone got any pics of one installed?
(yes i have searched)

Thanks!

as long as you match the threads, you'll be fine.

hmmm...a glow in the dark knob and a thicker piece of material for the R, lockout. Should fit fine, but I was much happier when I went for a weighted knob, that made a much bigger difference. I suppose I don't see the appeal of this.

I've never quite understood the shift knob thing. It there a performance advantage that I just don't understand?

Can you expand a bit on the difference that a weighted (I assume heavier than stock) knob makes?

smoother shifts, quicker shifts, easier shifts.

I'm guessing it just crunches into the gears more easily.

It's cheap, and i like round knobs. I find stock a little too thin.
Plus for some reason I like glow in the dark stuff, must be the kid in me!
Sickspeed has some nice knobs, just wondering if anyone has installed one and how the fitment is!

Shiftknob choice or a perceived performance advantage isn't a placebo or anything like that, it's a preference. It's the object that your hands interact with the second most on the entire car.

Some people want different shapes or stuff that looks cool, and some people want either heavier or lighter knobs. Again it's all preference. Aesthetics aside, there is some obvious physics to go along with a heavier or lighter shift knob. It's just like swinging a heavier or lighter hammer. A lighter knob is going to be able to start moving easier, but isn't going to have the momentum through the shift of a heavier knob. This will completely change the way your shifts feel and can sometimes be the difference between something that is very notchy or buttery-smooth.

I find that most people prefer a heavier weighted knob on cars equipped with short shifters. With the change in mechanical advantage of the short shifter it requires an increased effort to get into gear. The heavier weight (and extra momentum gain) from a weighted shift knob can alleviate that increased effort, and really changes how the shift feels.

The weight will also change the way you feel the vibrations from the transmission coming through to your hand. More weight = more damping. I barely feel anything with my weighted knob, but I sure do feel a lot when i switch to my delrin knob.

So there is a ton of preference and aesthetics in shift knobs, but there is also a method to the madness and some not so obvious physics at play. Don't forget how these metals react to temperature changes. A very large metal shift knob will get hot when its very hot out, and it will get cold out when it's very cold out due to its large thermal mass. A delrin knob or plastic or even glass knob will be more resistant to these temperature changes, but usually won't have the weight advantage (or disadvantage if it's not your thing).

We carry both weighted stainless knobs, and delrin shift knobs for that exact reason. But if you want the best of both worlds look at Raceseng's lineup of knobs, as they have weighted delrin in some pretty sick designs.

Let's discuss the physics at play, are there any not-so-obvious physics about a shift knob that have an effect on the physics at play inside the transmission?

Would these physics be good for the transmission?

If you were to add a weighted shiftknob that was so substantial (something close to the weight of your hand and arm) over time you would start to have a force that would be constant pushing the shift forks into the synchros. Exactly like why you shouldnt rest your hand on your shifter while you drive, or keep your clutch pressed in when you're at a stop light. You're doing extremely small amounts of wear, but for very very long periods of time.

But that would be a ridiculously heavy shift knob, something in the range of 10lbs. Whereas a heavy weight shift knob is around 1-1.25lbs. So the forces are significantly lower than the situation where you're resting your hand on the shift knob constantly while driving.

So in short, any additional wear would be negligible from weight alone. And as far as increased wear from shifting into gear very aggressively? You can expect that to be the same. it's a very short momentary force, and pretty much unnecessary, especially with a weighted knob. So again, no negligible difference or damage to the transmission as a result.

Thanks. I appreciate that.

I take issue with the assertion that a weighted shift knob somehow magically allows for faster shifting.

As far as personal preference, of course! I'm always fiddling with custom setups.

Oh most definitely man, I've been fiddling with custom set ups my entire life. In this specific example I have three shift knobs that I rotate between, and each one of them isn't one you can purchase. Two of them are prototypes that didn't make it, and one of them was never intended for shift knob duty at all

But just for super-duper-clarification for anyone who might read this: A weighted shift knob isn't going to give you faster shifts. It's strictly a personal preference thing as far as how you like your shift to feel. Buy what you like, and if you don't like it then try again!

I think others touched upon it, but I purchased a Textured and Weighted shift knob. There is a 'feel' to it. The throws feel smoother and faster, because you have the weight of the knob, on your side. Like someone else said, you touch the shifter so much in the car, it was worth the 40-50 bucks to me.
