Upgraded to 20” Chrome LTZ rims and low profile tires! Love the look. Looking at it now I think I would have gone with a tire that has a bit more sidewall. At first, the tire shop I had install these tires don’t even BALANCE them! They rode terrible. Afterwards, it’s a whole lot smoother. Only thing is that now because of the low profile the ride is still a little rough. Mainly on stretches of freeway that aren’t so smooth… Nothing I can’t live with! I’ve been debating between 4/6 and 3/5 drop for the longest but I think I’m just going to start at a 3/5 for now and eventually get a little bit more beefier tires. Maybe a 265/50r 20

4/6 or bust


I love the look of a 4/6!!! It’s what I really wanted but I only worry about clearance issues. We have a lot of dips around here and I drive a lot of freeway miles. I do plan on installing helper bags ! But as for front clearance I’m unsure 😕

Here's a 4/6 next to my +14"

20" difference back bumper height.

Do the 4/6 sir

Wow nice! That looks awesome. Maybe I just will do the 4/6… everyone says I should so I think I’ll listen to them lol. I bought the Hypertech Speedometer Calibrator this morning so I can correct the speedometer. Didn’t think the difference in tire size would make the speedo be off by as much as it is. It’s only about 3 MPH on the freeway but in the end I would just rather have the truck running good and shifting right ! 

 

Do you remove the lower air dam on the bumper for more clearance?

You could remove it. I would do the drop and see how close it is to the ground.

4/6 on a K2XX is really not that low. A lot of people around me do a 5/7 or 6/8 and I live in a city with some of the worst roads I've ever drove on. Helper bags will be good if you still tow.

 

I would remove the air dam just because it looks ugly, if we are talking about the same air dam

Thanks ! That's good to know. Honestly I think I might regret my tire size choice lol. I took the tires in for balancing but man they still get bumpy on the freeway. Dunno if it's the tread or not. I'll see how long I can live with it. Might upgrade to Michelin Defender LTX 265/50r 20 in the near future. Rn I  have Goodyear Eagle GT II.

The air dam I mentioned is the lower part of the bumper that seems like it'd get hammered on steep dips and driveways , mine actually looks like the previous owner might've jumped a curb at some point cause the passenger side looks a little shredded lol

Post a picture of it, I think I know what you are talking about but want to be sure.

 

No idea about those tires. I am at 265/50r20 on some Falken tires I believe. You may be able to get some taller tires in a K2XX though

I think we’re on the same page. The air dam I was talking about is the lower part of the plastic lower bumper that can detach. It’s a really skinny long piece

Yeah take that off it looks ghey


Definitely gonna do that then! And definitely once I get some more $$$ gonna get new tires. These look cool but eh the ride isn’t worth it. I had a GMT800 (06 RCSB Silverado WT) and this is the wheel and tire combo I wanted. I know a lot of guys run 275/45 20 on GMT800s so I thought we’ll since i don’t have the cateye anymore might as well do it to the K2XX 😅 I’m a noob to trucks so yeah I guess I didn’t think that over lol. I’m so used to tuning with carburetors and lowering with blocks and cutting springs this is all brand new to me !

Like I said I run that 265/50r20 tire and wheel setup on my truck. 2/4 drop but I think I am a bit lower than that on the front. This is my fitment

As you can see they fill my wheel wells up much more than yours. I would be looking at bigger tires.

Another option on the air dam... On mine and it looks like on yours the license plate mount is part of it. (Although my Silverado isnt dropped but leveled instead ) I didnt want to drill holes in bumper to mount the license plate so the air dam had to stay. I always thought that it just sat too low. I came across several threads here that mention it is actually 2 long pieces screwed together. You can take the bottom part off which will give you more clearance and just put top half back on.

I hate to say it but those Goodyears are on the bottom of the list on tires myself or most guys on here would buy.

      2023 DRW Wheel Liners

      By SFC Retired · Posted

      Did have to make 1 modification because of the WeatherTech rear mud flaps and that was needing 3 longer screws than what came with the install package. 😄

      Picked up the liners yesterday. Installed passenger side WITHOUT any modifications. All mounting holes lined up perfectly. Rain is interfering today with drivers side. Very Happy! Will add pics when finished

      OCI, not when but why?

      By KARNUT · Posted

      As a matter of amusement I’ll leave this conversation with this. Do you beat the government average fuel estimate? Statistics are a guide to me. Not a rule. Someone once said I have to have the last word. If true and possible may be. I’ll blame that on working in a family business.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That is a fair point, and I agree that trying to log “everything in the truck” would be the wrong direction.   There are a lot of modules and a lot of traffic. If the product became a full-truck datalogger, the amount of data would get huge very quickly, and most owners would never use it.   I think the first useful version would need to be narrow: - powertrain-side event evidence - selected high-value parameters - communication / voltage / reset events - pre/post event window - short report first, raw log only as backup   One distinction I should make is between active OBD/PID polling and passive bus capture. If you are polling PIDs through OBD, then yes: the more parameters you request, the lower the effective sample rate becomes, and you are adding diagnostic traffic to a vehicle that is already busy running itself. With passive CAN capture, the recorder is not asking all the modules for data. It is listening to traffic that is already on the bus. So it does not consume vehicle bus bandwidth in the same way that a scan tool polling hundreds of PIDs would. But your point still applies in a different way.   Even if passive capture does not add bus traffic, the recorder still has limits: - processing rate - storage rate - timestamp accuracy - decoder workload - event filtering - report size - user attention span   So the answer cannot be “log everything and let the user figure it out.” The product would need to store enough raw evidence to be useful, but only decode, graph, and present the important parts around the event.   A practical report should probably show: - what triggered the capture - how much pre/post data was preserved - which selected parameters changed - how those values compared to baseline - whether the same pattern happened before - whether any voltage, reset, bus-off, lost-message, or communication fault occurred - selected graphs around the event - raw data only as supporting evidence   So I agree with you. More data is not automatically better. The real product is the reduction from raw data into a useful event report.

      That makes sense, and I agree with most of that.   I think the product would need both: 1. a default powertrain template, so it is useful out of the box; 2. user-selected priority parameters, so the owner or shop can choose what they want to see first.   Different users are going to care about different things. One owner may care about oil pressure and voltage. Another may care about misfire trend, AFM/DFM behavior, or U-codes. A shop may want communication events and repeatability first. Your baseline point is probably the most important one. Raw data is not very useful unless the report can show what normal looked like for that vehicle under similar conditions.   The way I would think about it is: - start with a basic known-good baseline - learn normal behavior for that specific vehicle over time - allow the event to be overlaid against baseline - show whether the event was a one-time spike or a repeatable pattern - provide a simple severity level, but with clear limits on what that severity means   For example, early severity could be something like: - Info: event captured, no obvious abnormal pattern - Watch: value moved outside baseline, but not repeated - Warning: repeatable abnormal pattern under similar conditions - Critical: communication loss, voltage drop, bus-off, reset, or severe repeated event   I would not want the first version to say “replace this part.” That would be overclaiming unless there is repair-confirmed data behind it. It would be more honest to say “this pattern deserves inspection.”   On the OBD port question, I think OBD absolutely has a role. OBD is probably the right place for: - DTCs - freeze frame - VIN - calibration information - normal scan-tool parameters - Mode 6 / enhanced diagnostic data if available The reason I am still looking at an ECM-side recorder is that the failure may happen before anyone connects a scan tool. If the owner plugs in a scanner after the event, the pre-event evidence may already be gone unless the ECU happened to save it. So I do not see this as “OBD versus ECM-side.” I see it more like: - ECM-side recorder: always armed, rolling buffer, event evidence - OBD/DLC companion: DTCs, freeze frame, VIN, calibration, normal scan data - phone/cloud: status, notes, upload, report generation, notifications   I agree that phone connection and push notifications would be useful. I just would not want the phone or cloud connection to be required for capture. The recorder should save the event locally even if the phone is not connected. The phone should help with event marking, download, notes, upload, alerts, and report viewing.   For a default GM V8 event report, would this list make sense? - RPM - calculated load / MAP - throttle position - vehicle speed - gear / torque converter state if available - coolant temperature - oil pressure - oil temperature if available - battery voltage - commanded AFM/DFM state if available - actual AFM/DFM state if available - misfire counters / roughness by cylinder if available - fuel trims - relevant U-codes / communication events - bus-off / lost periodic message / module reset / voltage drop events Which of those would you remove, and what would you add?
