18 and 20 inch Drag Radials Pros and Cons

Okay, I am tired of the inconsistency of street tires at the strip and getting close to pulling the trigger on DOT drag radials. I need help from those of you that have experience with 18 and 20 inch wheel set ups.

Presently, I have an M6 with Solo high flow cats, Haltech CAI w/ADM scoop, Pedders street 1 bushings and chromoly trailing arms. Future mods will be gears in the short term with headers and cam a year or two from now.

I like the sleeper look and think 20 inch drag radials on widened stock wheels would be cool. But I have heard the 20 inch radials can lead to parts breakage and may not hook all that well. Are 20 inch drag radials a waste of money that won't get me consistent 60 foot times?

Getting a Weld or Bogart 18 inch DOT drag radial set up would allow me to change the look of the car from time to time. It seems that this is what I will ultimately need when I get gears, cam and headers. Its definitely a more expensive route, but if I can get good consistent 60 foot times with less strain on the drivetrain, I will probably go this route.

Sacramento Raceway generally has great air with poor traction. I only go a few times per year due to the track being 2 1/2 hour drive away, so perfecting my launch technique has been tough. With so few times at the track, I don't want to go home frustrated anymore. My car is a daily driver, the set up I go with would be used to drive to and from the track only. Help me make the right choice.

IMO, 2-1/2 hours away is quite a far drive on DR's. In your situation, I would just try putting some Nitto NT555R's (275's) on your stock wheels and see how you like them. They are a fairly decent drag radial that will still allow daily driving without wearing out too fast. Or you could widen your wheels (or just buy some wider aftermarket wheels) and put 305 NT555R's on them. Beyond that, the other "more serious" drag radials are softer and that 5 hours of driving to and from the track will take a toll on them. If you really wanted to, you could downsize all the way to 17's with the right wheels and suspension parts without changing your brake set-up. But again, that is for a fairly dedicated drag set-up. Personally, I would try out the NT555R's and see how you like them, they should be a pretty good improvement over street tires.

I have read the 555's don't hook up all that well, but sometimes these comments come from guys with 600 rwhp. Do you have experience with them on a bolt on car at the track?

I have the Nitto 555R drag radials in 275/40R20 on my 2011 L99. Mods are LT headers, HF cats, cat back exhaust and JRE email tune. I've only had one day and one run out of a dozen days and 70 runs that the tires dead hooked, and that was at Valdosta on a cold December saturday. Every other run (at both Valdosta and Silver Dollar) I experienced wheel spin. I will admit I'm a novice, but I'm getting rid of those tires ASAP.

I've run a set of 275/40R20 NT555R's on my bolt-on L99 and went 1.85 with them last year. They are a definite improvement over stock tires, best I could go on stocks was 12.7 on a 1.92 and best I went on the 555R's was 1.85 as mentioned.

All 20" DR's are a little pricey, so also check around locally on CL and on www.tbssowners.com (Trailblazer SS) sometimes good deals on there. I've DD on mine in rain and they were like stock.

I'm now also running a set of 305/18 NT555R's on 18's, not stealthy, went 1.66 on them I have a converter now. I would only DD if you have a short commute like me, mine is 5 miles one way.

Comparison:

I drive around on a daily basis with stock tires. But for the track i run the same setup as PSJ. 18 inch C6 zo6 wheels with Nitto NT05R 305/45/18 drag radials.

I drive to the track on my normal tires and load my track setup in the car with a small jack. One in the trunk, one in the back seat with a tarp.

it is a 2013 zl1... car has went as fast as 1.51 and goes a 1.60 spinning... no excuse to have 17s on a auto car in my o.p... my buddys car (I cant remember his screen name on here is a auto ss with whipple ect... car goes 1.5s on nittos, but his car is not near as consistant as mine and he has a few susp mods..

Eventually that 20" dr will hold you back. And you aren't to far from that point.

At what point do you think 20 inch drag radials become a significant limiting factor? Is it 12.0's, 11.0's or some other factor such as simply not giving a great 60 foot time no matter the overall ET?

Just about where Baron is. 700 rwhp and low 10's. You could prob drop 10k on a full drag suspension and go a little deeper but it would be smarter to change the tire/wheel set up. At 700 rwhp I would expect much better than a 1.5x 60'. Something in the mid 1.4's is possible with a better tire. So B could prob go much faster with a different tire but he wants to max this setup out first. Time will tell what that point is.

My 275/40R20 NT555R's will hook at the track but ONLY if I leave off idle or roll into it. If I try to stall it up and leave hard on the converter like its suppose to I will get massive wheel spin. Its a auto car with a converter 440rwhp and stock rear gears. Since you are adding gears later on I would recommend the 18's with a 305/45R18. Cheap wheels for those would be C6 ZO6 front replica wheels or TSW Nurbergrig's. I thought the 20inchers would do the trick but found out otherwise. I'm sure a 315 or 305 20 would do better but still wont be as good as the 18's. I wish I had got 18's to begin with before spending over 700 on the 20's. The only advantage of the 20inch DR over the 18 is that it will look better for daily driving.

I spoke with the Mickey Thompson Tech and he recommended the 26x11 R17 ET Streets. Its a bias ply tire that is not appropriate for longer street drives due to the heat building up. He said they don't recommend Drag radials for manual transmission cars. This really complicates things. I guess if the drag radials are not optimum for us M6 guys, the question is how satisfied are you with drag radials on your manual transmission car at the track? Are you getting good consistent 60 foot times?

Lol 26s are way shorter than stock. Our stock tires are 28.5 or so.

Yea, I know. My Michellin Super Sports are 27.6, with 26 inch tire, fender gap would be an issue, but on the plus side it would have the benefit of a slight gear change.

I agree with PSJ... 26 is too short as that will also simulate a rear gear ratio change. I think when i looked it took the stock 3.45 up to a 3.80ish range.

I run 18in drag radials as stated earlier, with a twin disk clutch. And although its not as consistant as a slick... it can get job done. I really dont think a slick is necessary as there are members that have pulled of 1.5x 60fts repeatedly with a drag radial.

as for my results i usually average around the low 1.8x's and on good launches dip into the 1.7's... my goal is to pull off a 1.65 or better 60ft on them which i see achievable.

if you are going to race competitevly and frequently... then look into a V6 conversion in the back, some Weld 17's and slicks.

If you do it from time to time for fun. Just stick with 18's and DR

Agree with everything you said, except....You don't need a V6 brake conversion to run 17" Welds.

So, you guys are getting smaller then 20" rims to fit with the SS brakes? Interesting, cause i know when i did the V6 to V8(SS) brake conversion i was told i have to run 20" rims to clear the calipers.

Not True. With a few minor modifications, there are a few 17" wheels, and several 18" wheels that will fit over the Brembo Brake Package. For 17's, you will most likely need to modify your lower control arm, or buy aftermarket BMR arms. And all will require the emergency brake cable to be secured out of the way so that it will not rub. If you have OEM Brembo brakes on the front, you will need to cut off the brake pad resonators (roller skates).

Yes those are ZR1 replicas... they can be found at factoryreproductions.com ... believe they are about $200 each and make sure you get the offset +40 to fit correctly.

And Blazin1... thanks for correcting me, i meant to write a v6 conversion OR the welds. But you absolutely correc that the 17 welds fit over brembos.

Thanks for the info, even 18's i would think better then the 20's. Shame my 15's drag radials from my 67 wont fit.

There are a couple companies making 15" conversions....but that's a complete brake package swap and some suspension parts too!!! Fairly big $$$$$$!!! Besides the wheels wouldn't work anyway....completely wrong offsets.

Unless you are going single digets you just dont need anything but a 305 m/t drag radial on a 20" wheel lol
