I think we can do that

Happy New Year all! Let's keep this board alive for 2021.

Same. While having my GTP from 02-14, I built it for a buddy in 09 and bought it from him in 16. Going all out now while we're still on partial shutdown. Great way to pass the time.

Welcome back earth1. I'm still sticking by my project regal, even if it has been a garage queen for the last couple of years.

@  earth1 : (18 November 2020 - 03:27 PM)

I want to thank those who run this site for their dedication and for keeping this site going through the years. To have a really good Regal GS, one has to have an extraordinary level of dedication to the car that includes a long-term commitment to it, and not just a passing fancy. Similarly, to the people that keep this site going through the years had to have a similar level of dedication and commitment to keeping it going. I just want to tip my hat, pay my sincere respect to this level of commitment, and say thank you. I will try to contribute what I can. I know that these cars are 20+ years old now and a lot of people have moved on from them, but I want to be counted as one of the ones that stuck with them for the long-term. I hope to see others that love their Regals be active here in this site, and for the Regal community to support each other. Count me in.

I finally remembered my password and can get logged in. I have missed posting to this forum. Lots of things to add here from my own Regal GSE project.

@  ejguillot : (20 October 2020 - 03:32 PM)

Well, welcome back!

Holy Crap I got in...finally remembered my login

@  de.regal : (04 October 2020 - 10:50 PM)

Still lurk every day

@  tpivette : (03 October 2020 - 02:32 AM)

Sucks these forums are as vacant as they are... oh well, there's still the faithful like us!

@  kevandkaye : (27 September 2020 - 02:40 AM)

Yet still, we lurk. :o

@  ejguillot : (27 September 2020 - 01:08 AM)

Yeah, Facebook took over and killed forums.

@  dezldave961 : (26 September 2020 - 03:24 AM)

Ya, most of the original wave of active members have changed vehicles to something (probably) less mod-friendly, with the occasional person in an LS or Hemi that they do some bolt-ons to. Kinda sad that forums faded.

@  ejguillot : (23 September 2020 - 09:02 PM)

Finally updated my signature to match my current Buick.

@  ejguillot : (10 September 2020 - 03:20 AM)

Things are terminally quiet around here...

@  dezldave961 : (29 July 2020 - 04:06 AM)

Just became a moderator on 3800Pro, so that's fun. I know it's gone thru a couple hands since Intense got sold, then that guy sold the forum. Not sure what that'll help, but it's something.

First off is the mother of all hub sizes and bolt pattern lists. Don't get discouraged if the wheels you're looking at don't have the same hub bore as our cars. They can still fit. If the wheel's bore is too big, you can use hub-centric rings. If the bore is too small, you can send the wheels to a machine shop and have them bored out.

Next is a wheel offset calculator. Use this to get an idea of inner and outer wheel clearances. The offset number is measured from the center of the wheel width. Thus, a 35mm offset on a 6" wide wheel is totally different than a 35mm offset on an 8" wide wheel. For reference, stock wheels are 6.5" wide and have around a 52mm offset. Not positive on that, but it's within 2 or 3mm of that.

Last but not least is a tire size calculator. Stock size is 225/60/16. Use this to get an idea of what your new tires will look like in comparison to the stock ones, and/or to match the new size as closely as possible with the stock diameter/circumference.

Other useful info I have for Regals/w-bodies:
Offset Range: 34 to 45
Wheel Size Range: 16x7.0 to 20x8.5
However, I'm not sure how reliable the offset and size range info is, because stock wheels are actually 6.5" wide, and I've definitely seen guys run 9" and wider wheels before. So, take it with a grain of salt. Still gives you a decent idea.

Very nice thread Aaron! There's a lot to consider when selecting the right wheel/tire combination for your car. I sometimes wonder when someone comments "those wheels really fill out the wheel well" know it's generally an optical illusion. For instance, if you increase your wheel size from 16" to 17", the profile of the tire changes to maintain the same rotational diameter. So while the wheel gets taller, the sidewall grows smaller. Of course, you can go to a taller wheel and tire profile, however than you need to make adjustments in the speedo/odometer calibration settings to compensate for the decreased revolutions.
