If we’re talking bone stock out of the factory, it might be a very close call between the w-body2 (the MS2000 platform(“97”-“03”) GTP Grand Prix & the 1990 Cutlass international. If we’re talking modest mods, it’s going to be the GP (“97”-“03”) & if it’s a full out build, then there is no competition. It’s the GP (“97”-“03”)! Why? I have driven all of them extensively in testing & owned quite a few as well. So; I’m not being prejudiced or a smart guy! It’s just you can’t argue with physics! Now there are minor things that can be done to help improve the inherent physics incorporated into a platform/model & some more than others, but they tend to be somewhat limiting. While you might think all models in a platform have the same physics, they do not! Height, width, wheelbase, weight distribution, etc. are all different & consequencally so goes the base physics that limits the overall performance. Furthermore Super Buick is correct! The skidpad test is just one data point & while it measures lateral g acceleration, it is not a true test of an active suspension & how the suspension components work with regards to the handling. What it is, is the test of three things! The adhesion of the tire coefficient to the pavement, the stability of the components to hold their positions relative to geometrical physics that were designed into the vehicle, I.E. CG & RC, etc. Plus the moment of inertia! But the moment of inertia that is measured in the skidpad is minuscule in comparison to performance handling! Which is a critical element in car handling! What the skidpad test can’t test is suspension rollover, hard instant response handling like slalom racing, accelerometer force generated by such aggressive movements & platform resonance frequency, in which the latter can drastically influence the total performance of suspension performance.

Hey guys - as part of my resto of the 1990 Quad4 Cutlass International, I'm looking for a pristine-ish "donor car" (to either use the body so I dont have to spend a ton on painting the 1990) or for the unobtanium trim bits etc. I did a body swap on my STE restoration - so it ended up with the 1991 drivetrain but I used all the 1992 electrics (the body harness and underhood (non engine) harness was different from 1991 to 1992, but the engine wiring was the same, so it worked out well. One of the cutlasses Ive found is a 1988 (2.8 auto).  I know obviously the engine harness would be completely different from a quad 4 to a 2.8, but does anyone know how different the "other harnesses" are from 88-90?  like the underhood fuse stuff, interior stuff (assuming same options of course), etc?  

UPDATE: I was just advised the mechanic is going to elect to go the RTV route; the head will not be pulled for this job. I think you can all hear the huge yell of relief coming from this desk. I'll be sure to post once completed. 

Absolutely not in the TGP after the roads are salted, and never when its wet to avoid road spray. But for the `94 CS I might like to DD it part time during the year.  It's rotors have been long overdue for replacement and for a surprisingly small price difference the F/R kits get everything from one shipping location vs all over.
