Well, since the topic has now come up... I figured I'd let everyone in on my side project. I was going to surprise everyone, but since this has now become a topic of discussion, I figured I'd share the knowledge on the topic I have gained so far. My Silver SRT-8 has been on floor jacks for several weeks now as my rear tires are being split and all the rims chromed. Should be a couple of more weeks and the car will be back together and on the road with 10.5" - 10.8" rims on the rears and some 280 - 295 40's on the rear and 245 40's on the fronts. I haven't fully decided on the rears yet, since there is a very limited selection available in this range of 20" tires. I am trying to stay as close as I can to over all diameter, so the computer doesn't barf all over the place.QuikSilver said:Ditto on widening the wheels - Located a specialist in Indiana that has custom built wheels for years on many "Rods" and will do each rim for $225. He adds the width to the "inside" so they will tuck very nicely!
I'm thinking of 20x10 in the rear and going with the tire set-up f/the GCherokee. (255/45 & 285/40)
If I don't go that route and get more radical then I'm looking at going 20x9.5 in the front with 275/40 and then 20x11 in rear with 315/35. The second route obviously will be a little tricky but I'm confident it can be done!
I plan on putting in the 180 thermostat and lowering pressure in the tires this week. I've got enough baseline runs at all different outside temps to be able to compare with added "tweaks". I'll keep everyone informed!!:naughty:
Also as a side note, there isn't enough room, even with rolling the fender wells for the 11" split and widen to be a realistic option. I will be having the fender wells rolled as well, and might not be able to get the 10.8's in there. I think 10.6" will be a safe compromise.
The split I am doing is going to be less than the $225 mentioned in the (GS Supercharger report - "Strap yourself in!!") post #32, so for those seriously considering doing this, I might be able to work out a group buy. Professional work done on a very expensive lathe and this is all this guy does for a living. Of course Cincinnati is really close to Indiana, so it might actually be a real option for you QuickSilver.
