I don't think you understood my question. Here's what I need to know.....
+ Is the OEM F3 swaybar beefier (stronger, heavier) than the OEM RT swaybar?
+ If it is, will replacing the OEM plastic links with metal links (keeping the OEM swaybar) offer a noticeable improvement in the handling?
All very good questions. Here is a general idea of what you can expect. There are variables like weight loading and riding style. The heavier you are loaded and or the more spirited you ride, the more you will appreciate an upgraded sway bar. But you don't have to ride like a wild person or be loaded to the gills to love the bar either.
The plastic links will stretch on one side and compress on the other while turning. The greater the lean, the more of this effect you will get. This action absorbs some of the energy transfer that the sway bar is trying to accomplish. I do not know of another vehicle on the planet that uses a non-rigid sway bar link. Though to BRP's credit. In most cases, on a stock sway bar, these plastic links do seem to hold up well enough. Replacing these links with a rigid part allows the sway bar to operate at peak efficiency and most notice an improvement in handling. But the main reason I require that my link set be installed with every bar kit is that my bars tend to break the OEM BRP links. So my links not only make the bar more efficient, they make it safe. And we can all get behind that.
One interesting note about this is that the parts list for the new 2020 RT shows that BRP is still using the same plastic link set as every other Spyder ever made.
The RT is a heavier vehicle than the F3. Sits higher, has more storage/weight capacity, and commonly has a passenger and maybe even a trailer in tow. All of which makes it want to lean and dive more than the f3. So, the need is greater and it rightly comes with a heavier sway bar than the F3. Putting the stock RT bar on an F3 will give you a fair amount of improvement. However, my F3 sway bar is significantly stronger than the OEM RT bar. Many F3 riders have gone from the stock RT bar (with or without rigid links) to my F3 bar kit. In every case that has been reported back to me (and I do get a great deal of feedback). Owners have been impressed with the improvement over the stock RT bar.
Though I have never heard it put quite this way. The appraisal by Peter Aawen is accurate.
The fact is, the newer Spyders handle pretty well right out of the box. Many tell me that they are happy with the way their F3 or RT handles. And how they see no need to install an upgraded sway bar. When people tell me this, I always ask them; 'Have you ridden an F3 or RT with my sway bar kit installed?'. In every case, they tell me, 'No.'
It is not uncommon for a potential customer to call saying that they don't think they need my bar kit. But that they've read or heard so much about it. Or that their friends are telling them that they need it, that they are going to finally jump in and get one. Some say; 'Against my better judgement.' I always tell these customers the same thing. 'If you don't want to do this, don't! It's your ride. Don't let others tell you how to do your thing.' But they almost always buy the bar kit anyway. And it's like clockwork! I get a call or and email or see a post here where they say something like; 'I wish I'd done this a long time ago. Didn't know what I was missing.'
I understand that all of this sounds self serving. That's why I don't always jump in on these conversations. Those who have installed my bar kit are honest and accurate about the statements they make so I don't feel the need. To me, it's just a great deal of fun to have stumbled upon something that makes so many people so happy. I don't have to hype or push. Just lay out the facts and let the customer decide. To me, that's just the way it should be.
I enjoy riding. And I love my Spyder. I know most of you feel the same way or you wouldn't be here. That's what it is all about.
