Got bored and started making build video...

@  dezldave961 : (04 May 2020 - 04:05 AM)

I need to hunt down the little black trim bar that's at the top edge of the GS rocker panel cover, for driver's side between rear door and wheel well.

@  ejguillot : (03 May 2020 - 02:42 AM)

I've been on there too. I hope this forum is kept open, there's too much info to allow it to be lost!

@  dezldave961 : (24 April 2020 - 10:25 PM)

I've been monitoring GrandPrixForums and 3800Pro (don't have FB)... also hopped on TurboBuick, but 99% GN chatter from boomers

Everyone at home, plenty of free time.

@  dezldave961 : (20 March 2020 - 04:18 PM)

Pulled turbo engine, prepping MP112 setup... also doing some work-from-home stuff

@  tpivette : (19 March 2020 - 08:57 PM)

So far so good. Still working, fortunately.

@  ejguillot : (16 March 2020 - 03:46 PM)

how's everyone doing? With coronavirus and all that?

@  tpivette : (25 February 2020 - 02:35 AM)

Just got my GS back on the road. Wife is pressuring me to sell it... don't know if I want to or not

@  monte0 : (17 February 2020 - 05:04 AM)

Popped on to see how things are. Been a couple years...

@  ejguillot : (14 January 2020 - 10:36 PM)

Hope the new year is treating everyone well..

@  ejguillot : (16 December 2019 - 01:55 AM)

Hi all. Decade is coming to a close... I'm feeling a little old!

Hi there. Some of us are working to keep these cars alive and running. Glad you had a good 15 year run.

@  opera_bob : (30 November 2019 - 08:39 AM)

Every time I see an Old Buick I have major respect for it. I know what kind of torque these cars make.

@  opera_bob : (30 November 2019 - 08:38 AM)

I sold my 2002 GS back in 2017. She was falling apart all over the place. So I sold her and bought a 2017 Focus RS in 2017.

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.
