Any car with the 392 will be the street-race car from now on. My 15 SRT amazes me every time I drive it (23,000 miles) 24-5 mpg at 70. Rear tires are the only thing holding these engines back (I think mine were made with grease) lol Thats why put these on Specs on your rear wheel and tire combo???? Brand and backspacing on the wheels especially. Race Star 92-711452B , from Jegs, they are 17x11 +2mm offset [ 6in] Back space, had .500 machined off the mounting face, & shorten the shank on the lug nuts ,the wheel manufacture said they are made to do that, so now they are +14.7 mm [ 6.5 bs] they just clear the brake calipers ,anymore Back space & they would hit, Tires are 390/40/17 M&H , I had to put shorter sway bar links & heat up the plastic inner splash shields & massage them for clearance , they work great, I run the same tire on my 68 Charger & they hook awesome, still have not made it to the track in the Challenger, lots of other stuff going on, will try to make it this summer,fall. also I have the Lil Devil flares, the tire tread is just barely inside the edge, I also took all the neg camber out so it plants the complete tread surface not just the inside treads.

Thanks, exactly the info I needed!  I've been trying to figure out a combo to go with for some 17 inch drag radials for the back of my Challenger SRT.
Kayse can't keep up at all now. lol

Most people just bolt on a set of the correct offset 17x9.5 to 17x10.5 wheels, put on shorter end links, tweak the inner panels for clearance and call it done.
Or, go with 18x10 to 18x10.5 wheels and tweak the inner panels; the shorter end links aren't usually required. That was my approach, FWIW.
Either way, that's good for 305/40R with 18s (28" tall) or 305/45R with 17s (28" tall) or 18s (29" tall) while skipping the need to custom-fit the wheels to the car.
Just my $.02, since you mentioned looking for 17-inch options.

I went through all the extra work because 1 I wanted a 29.5 tire 2 I like the Lil Devil flares & wanted to fill up the wheel well, not fond of the factory wide body flares, the wheel I have are for a factory wide body application & then cut down, IIRC it was $ 75 for both

@csk - Oh, I think your car looks great.  I only wanted to point out that the steps you took aren't required simply to add some extra meat under the car. A set of Lil Devils flares would like right at home on mine, too.  But that's down the priority list at this point...

Thanks Brad, I understood what you were getting at & glad you posted a bolt on combo for our cars, not everyone wants to go through the process I did, I was also looking for the old school look of a dished rear wheel, love your 1320, beautiful Challenger, I REALLY like these cars !!!!!

I like the VMS wheels better than mine, but opted for cheap(er) cuz additional wheels weren't in my original 1320 budget. Those VMS look similar to some Welds that I also think are very cool (and even more expensive). Simply because of price, I grabbed some of the Race Star Series 95 Recluse wheels that are now discontinued and can be found for $130 each in remaining sizes. If you go directly thru Race Star, they'll add another $40-50 per wheel for shipping. If you can get 'em from Summit (not as many size & color options), then the shipping is covered. I ended up getting some from both, depending upon who had what in inventory. FWIW: Race Star --> Click on wheel size & color displayed to check inventory on hand SummitEDIT - Mine are the gloss black Recluse wheels, but I like the gunmetal gray w/ machined face, too

Thanks for the info on the Race Stars. I definitely like the pricing. The question now is which color would look best on the car.  I like the machined face on these, but not sure about adding another color like metallic gray. If only they were black with a machined face... ![[Linked Image]](https://static.summitracing.com/global/images/prod/xlarge/rce-95-010252gp_xl.jpg) I love chrome. I've always thought that the wheels are the bling jewelry on a car.  ![[Linked Image]](https://static.summitracing.com/global/images/prod/xlarge/rce-95-010252c_xl.jpg) I've never been a fan of solid black wheels on a car, but considering the yellow and black theme on the car these aren't bad. ![[Linked Image]](https://static.summitracing.com/global/images/prod/xlarge/rce-95-010252bc_xl.jpg)

Brand and backspacing on the wheels especially. How much shorter of sway bar links did you install? Source on them?? I bought the 17x10.5 Race Star Recluse wheels for the rear and doing a quick test fit for clearance the sway bar links will be in the way. The stock links on mine are 10 inches long. That looks like the only issue so far till I get tires. I got the 18x5 wheels for the front.

I have a 2019 1320 that I race in NHRA Stock Eliminator. The car started life as a flood car and was built to NHRA specs for the class. It runs in A/SA at a minimun weight of 3470 lbs with driver. It has a full roll cage and the car is converted to a solid axle rearend. The car uses a 904 transmission with an ATI 8" convertor. The engine must be built to NHRA specs, meaning stock cam lift and stock valve size, stock compression ratio, stock intake and stock throttle body size. The lifters and rockers are stock from Dodge. BBK's TB was approved so it could use a cable throtttle. Strange brakes are used with a 9 by 30" Goodyear tire. Best ET has been a 9.91 at 133 MPH Typical 60 foots are 1.32 -1.35 depending on the weather. Shift points are 7200-7500 and finish line rpm is around 7700-7800 with a 4.86 rear gear. Very solid engine so far. Thanks for reading. Dyno Cool car, when do you plan to have it out again?

Brad, thanks for putting up the link to the the Dodge Garage article! I'll have the car out at the Topeka double division race end of July and at the national event at BIR and Indy. We just completed a new 392/6.4 for the car, but have not had a chance to dyno it yet. Thanks!
