    Winter Wheels and Tires

    Here’s the wheels and snow tires mounted. The car is sitting a little high because it’s on jack. These are drag wheels with nokian tires. See my previous posts.

    CT5 exhaust

    here is a video from inside the car during normal driving with cutouts wide open. i think it sounds perfect. it is a little loud from outside - probably louder than most would like, but at this point in my life, i cant always worry about what everyone else thinks

    Spare tire kit

    where would you put the tire?? the trunk insert doesnt seem to be easily removeable? curious to see what comes up on my 13 CTS-V, i took an inexpensive drag wheels wheel and added a cheap slightly undersized chinese tire, then took the air out of it, and got it to fit in the well, and then i...

    CT5 exhaust

    if using full electric cutouts, the space right before the muffler seems to be a good spot - plenty of room and should not stick down below rest of car. also exhaust noise is less annoying if not directly under middle of car (personal experience). i didnt think too much about putting cutouts...

    Winter Wheels and Tires

    i will probably install the snow tires this weekend maybe - its cold here in NY but no snow yet. i'll post pictures then. i havent seen anywhere from michelin that using the summer tires below freezing could damage the tires. but i do understand that traction falls off when its cold out -...

    Winter Wheels and Tires

    I had nokian winter tires on my 13 v wagon for 8 winters. They were surprisingly great in dry and super great in snow. I wouldn’t race with them. But I strongly support winter tires not all season if driving in snow at any point. I won’t have these new snow tires in car for another week or...

    CT5 exhaust

    Would you prefer in car or from behind car? Truthfully it must be experienced from the drivers seat on the road

    Winter Wheels and Tires

    Well I will have my snow tires mounted up in a week or 2. It is possible I will add a spacer to the fronts to get back to stock offset. I would not put a 275 tire on an 11” rim but what do I know. I was thrilled to find an inexpensive wheel that fits. If anyone can find me a made in USA...

    Winter Wheels and Tires

    local dealer told me $800 each for front wheels for CT5 BW. not sure if they are available. this was in black. the Drag Wheels wheel i listed a bunch of posts ago, seems to fit, at a great price! i'll send pics of mounted on the car when I mount them in about a week

    CT5 exhaust

    Here's my vote for the best bang for the buck. i bought some 2.5" (could have done 3") exhaust cut outs (just the tubing, no motors), and used my hole saw to shape the tubing so it would fit around stock 3" exhaust pipes. then used the same hole saw to make holes in the stock exhaust just...

    CT5-V engine surge / "porpoising"

    i'm optimistic for now. it's too awesome of a car to be anything less did you have a similar problem?

    CT5-V engine surge / "porpoising"

    thanks for trying to help out. very nice of you. i'll see how it goes - if it happens more frequently, i will open a case with service department. meanwhile, i just racked up mile 499, so i need to find an excuse to drive 1 mile somewhere to let it all out

    CT5-V engine surge / "porpoising"

    i do not have PDR. i do have hptuners software scan tool, so if i can consistently reproduce it, i can record the event. It does feel like a manual bog - like when i try to drive my vintage mustang with a race engine - but when it happens on the CT5 BW, i downshifted from 3rd to 2nd gear to...

    CT5-V engine surge / "porpoising"

    Thanks @Mirza Grebovic has happened in my mode - custom mode - steering at touring setting, brake at sport, engine sound at highest track setting. i tried to change mode to tour mode while it was happening, but the engine surge continued even when i changed it for a few more seconds CT5.

    Winter Wheels and Tires

    SURPRISE!! When you buy 4 new GM tire pressure sensors, they do not come with the nut that holds them in place!! That nut is part 13581557 Plus also stock lug nuts are too large to fit these wheels, so have to be smaller diameter ones.

    Winter Wheels and Tires

    to sum up, stock CT5 BW wheels are 19x10 (20mm offset) in front, and 19x11 (50m offset) in rear. i think the center hub measures about 66mm. i could be off on any of these - here is the DR-80 wheel that is 19x9.5 the center hub is much larger than stock. centering ring optional but...

    Winter Wheels and Tires

    I’ll post some pics tonight or tomorrow with full details. Unfortunately sometimes I have to work to provide the means for what’s really important (snow wheels and tires). Sorry for the delay!

    Winter Wheels and Tires

    Good news!! I found relatively inexpensive wheels that fit CT5 BW!!! they are 19 x 9.5. the hub diameter is big, so could use a hub spacer ring to make perfect. i plan to use the same wheel on all 4 corners, with 275/35 snow tires. more info to come regarding model number, offset, etc...
