Ok folks, I'm installing some wheel ring lights on my SS. I have the red positive and the black negative but there is a blue wire that goes to the brake pedal switch. When this wire is hooked up and the brake pedal is pressed all the lights on the rings will turn red. I was told that this wire has to go to a wire on the brake pedal that when pressed will give you 12 volts. It can't go on the positive cause that will have them on red all the time. Does anyone know where this has to hook up on the brake pedal. Thank you all/
I am a fairly new Slingshot owner (since June 2019) (2018 SL), but have been driving and tinkering with it a lot.
So I thought I summarise what I have found (Thanks to the many contributors of the forum with good info that helped me).
I hope my experience and findings might help some other owners.
The biggest issue I had was the notorious rear end noise and whining.
There have been many different posts about the rear end noises, causes and possible fixes. Here is the summary of fixes that worked for me and some other experience and info I gathered.
The rear end drive noise and whining was really bugging me. Sometimes more, sometimes less, but always there. I had made sure my drive belt was clean and tightened per service manual specification, but is still so noisy.
I needed to find a solution and searched thru the different Slingshot forums (thanks to all the contributors).
I tried several different things and ended up with three things together to eliminate the rear end noise and whining.
I first changed the angle drive gear oil to a much thicker viscosity (see details below). That reduced the rear end noise quite a lot, but there was still whining noises.
Then I made sure the drive belt was adjusted per service manual specification, but it turns out that is way too tight, so I adjusted it to the specs see below. That made a huge difference and eliminated almost all the whining.
The last thing I did was to apply a sparse amount of Dielectric grease to the outside edges of the belt (see details below).
Rear angle drive oil: Change the rear Angle Drive oil to: Lucas Heavy Duty Oil Stabilizer 1 Quart (got it at O’Reilly Auto Parts). Use it at full strength (not diluted). It takes about 23.7 oz or .7 liter (700 ml) and takes quite a while to fill because the oil is so thick.
Drive Belt adjustment: The service manuals drive belt tightness specification is way too tight. No wonder owners have their angle drive bearings and seals go out. Most likely when you get it back from the dealer service or new it is adjusted per “spec” but way too tight. I am glad I did this with only 3700 miles on my SS with a too tight belt.
The Drive Belt tension should be checked with the car sitting on fairly level ground. The belt gets tighter as the rear suspension compresses (with passengers in it, going over bumps, etc). So when the car sits on level ground with no passenger in it, the Drive Belt needs to have some slack. I set my belt tension so I can move it ¾ “ by hand up/down which is on the looser side. I just wanted to see if there is any belt skipping (was not). I think between 1/2” and ¾” is a good range and will help prevent premature wear and eliminate most noise.
Belt lube: First, make sure the belt is clean. If you have not cleaned it, wash the belt with brush, soap and water and let it fully dry. This is done easiest with the rear wheel jacked up so you can turn the rear wheel and get to the whole belt to clean. You can also just keep rolling the car forward/backward to get around the whole belt.
For Belt lube I used CRC Dielectric Grease (is in red can, got it at Home depot).
Only apply a very small amount (about M&M size blob) in one area on inside and outside of belt and spread it out. Once you drive, it will spread over the belt all around the edge.
Thicker oil, looser belt and a dab of lube, all together, eliminated the drive whining noise on my SS and made such a huge difference in the joy of driving the Slingshot. Hope this helps somebody else too.
I have changed the stock shocks to the 3-way adjustable DDMWorks shocks. It made a big difference in ride quality and traction.
My SS has the OEM cold air intake, which gives it a nice grunty intake noise.
My brakes were little soft and not very strong. I bled them myself but did not get much better.
If you have weak and mushy brakes, don’t waste your time and money buying bleed kits etc. and try doing it yourself. I tried several times with vacuum kit etc.without getting much improvement. Finally I brought it to a dealer. Make sure they know how to do it properly and that they have the “Digital Wrench” which gets connected to your diagnostic connector and is needed to activate the ABS for proper bleeding. I Paid $ 100.- to get it properly bled. Very firm and good brakes now. Money well spent.
Other changes and add-ons I made to my SS:
Assault Industries Tomahawk Round Steering Wheel
Paramount Plastics Stealth Hood Vent Heat Extractor
Paramount Plastics Stealth 2.5 Mega Audio Shade Sun Visor
Foamskinz Transmission Tunnel Mats
Foamskinz Passenger Side Kick Mat
Ultimat Fitted Carpet Floor Mats
ZSW Trio Front End Side Grille Gap Fillers
Built-in garage door opener (DIY)
Rear swing-arm flap (DIY)
Great Windscreen cleaner: Plexus Plastic Spray Cleaner-7 oz Can (got it at Amazon)
Hope this is helpful to some other SS owners.
I love my Slingshot. It is so fun to drive.
Can you share a picture of the rear swing arm flap DIY and material used and process please
Does anyone know how I can wire Led's lights to signal with the turn signal when applied?
okay - so can someone tell me how to PM someone here - I found a link to e-mail (which I did) and a conversation link, but nothing to PM
Hover over the person's name and a window pops up. Bottom portion of that window hover over and it'll say create conversation
I use Pledge on all of SS. Works as good or better than anything out there. It’s crazy how well it shines.
Pledge as the furniture polish? On the body too? How about the black plastic?
What are you using to clean your windshield?
I use mine on a daily basis except when the forecast calls for rain. Love it in the winter or cold days since the engine air warms up the seating area lol
I'm with frehleycomet on this one.
My daughter is 21 and moved out as well, but as long as i'm still kicking I need to be close to her *Just in case*.
Just something dads must do.
On a different note.
frehleycomet if you still haven't gotten a new cone filter for your SS PM your address and I will ship you my factory one for free.
It only has a full 5 days of use on it
messaged you bud
frehleycomet , I feel your pain. Just look at where I live, it takes three hours to get to any good riding areas. And yes everyone says, why don’t you move?
Right now I have to live with it.
Good luck and enjoy riding.
I hear what they say about moving. Trust me if I were single and no daughter I would move but my wife won't move and I can't leave my adult daughter behind even if she's on her own now.
Does anyone know where I can get a replacement air filter for a 2018 SL. It is the round one without a casing. TIA
Got a place in town that will have one by morning. Thank you all for your help. Much appreciated
if you can wait a day or 2 try Discount tire Direct 255-35-20 - - I have used them to get new tires for the slingshot and they usually get to me in 2 or 3 days at the most. You can search by size and then use the filters on the left to narrow the search to the specific type of tire - - looking just now they have 11 of the Nitto 555 G2's in stock in your size
Discount Tires in my area said it'll be a week before they get them
Go to Discount Tire and they can fix you up. Many of us have gotten rid of the Kendas ASAP. My wife and I both use Nitto 555G2s.
Discount tire doesn't have them is stock and it'll take about a week to get one. Too long for my cup of tea
Just got a flat tire on the rear. Unfortunately the hole is on the side wall. No one around can fix it. Can I just purchase a new tire with a different brand name other than the one on it now ( Kenda ) as long as it's the same size 255-35-20
