Thinking about running my car on big and littles all the time. It's not a DD just a weekend toy and I'm not really worried about cornering I just like straight line speed. I was considering the 16" ccw drag pack with maybe some et street 2s out back.

What is a good size rear tire to run? I will be making around 650rwhp threw a 6 speed in a 98 C5. Let me no your opinions on this.

I've done it (with two different cars), it's not too bad.
As for wheels/tires, you'll probably want to go with 17" skinnies up front as the skinny tire choices are a little better (much better actually) in 17".
Rear tires, depending on the width of the CCWs (they're usually 10" in width) and your rear gearing (3.42s? 4.10s?) I would probably go with the 255-50s (ET Street Radial) as the other two 16" offerings (295-50 and 315-45 ET Street IIs) are a little too tall in my opinion.

I drive around town with the CCW drag pack also. Also go back and forth to the track with them. 22 miles each way.

YO-EL

I do too & its 80 miles each way.. been doing that for 13 years..!

I'm still thinking on it Ive talked to a few buddies of mine that have run them on the street and they are telling me to go with a good street setup on the vette and leave the big and littles for the track. I personally love the way drag wheels look on a c5

Has anyone ever done a test on normal front vs skinnies on E.T.?
The reason I ask is, when you get out of shape, the skinnies don't have the traction to stear the car as well as normal tires on the front. I'd rather have a slight ET reduction for the insurance to save the car if needed. I have had some oh crap moments on BAD tracks in 2nd and 3rd gear and I was wondering how much steering traction I'd give up with skinnies.
I will say, on some tracks the MT Drag radials don't hook up either in all gears.

I almost put my 9 sec TA into a house once, Lol
Turned the steering wheel, car just went straight.
Granted I forgot to tighten up the front shocks before I left the track and I was impatiently trying to get around some jerk going 7 mph but still-turning the wheel and going straight was pretty scary.
If you can just putt around and not get on the car then yeah its doable but if you start screwing around or you get into a situation where you have to stop quickly or react quickly then it could absolutely be a problem, don't kid yourself. You have to be VERY careful.
Skinny's are worth about a tenth in the 1/4 and help reaction time as well. Any drag racer who has a choice will run skinny's and if you have a vette then yes you are rolling on them on the way to the track-one tenth and better reaction times are a no brainer so just be carefull when running them on the street.

And depending on just how heavy one's standard front wheel/tire set up is (stock C6 Z06 and ZR1 fronts are quite huge) and just how light their skinnies are (not all skinny wheel/tire combos are created equal either of course), the advantage could even be as much as almost two tenths and 1.5+mph.

The main ones I'm considering are weld rts and ccw drag pack. I really like the billet specialties street lites as well.

If I run the welds I will more than likely run a 17x5 up front with a 205 size tire and some 17x11s out back with 295/45/17 et streets

LS1LT1

205s are a little 'wide' for only a 5" wide rim. I would go with a 195 or even the more common 185s (both M&H and Hoosier make skinnies in that size). Ideally, I would go with the 185s but on a 4.5" wide rim if possible.

I have street driven almost all of my past corvettes, mustangs and camaro with bigs n littles. I just love the look...

Chris Stewart

My son did back to back runs in his Formula. Went 12.41 with Z06 fronts and 12.37 with CCW skinnies, both at 109 mph.

LS1LT1

And that almost clarifies my point above.
CCW skinnies are not the lightest ones available (especially the original 16" versions or even the newer 17s with the M&H radials (instead of the bias plies)).
C5 Z06 (OEM) fronts are actually pretty light (the rims are only 17.5 pounds and the tires are non-runflats) to begin with so the weight savings (and ET reductions) would of course be minimal in that particular scenario.
There are also potentially changing wind conditions and even slight variances in staging location as well to consider but I will assume your son did that identically for both runs.

When going from a set of replica (factory sized) C6 Z06 chrome wheels/runflat tires to a set of Bogarts or Alumastars with an M&H or Moroso DS-2 bias ply tire I can assure you that you WILL reduce your ET by more than a mere .04 and you WILL trap higher after the swap.

Chris Stewart

We checked each CCW front wheel (with tire) was 10 lbs lighter than the Z06 fronts. Not the lightest out there, but they are sturdy and won't buckle when you kit a pothole.

Just curious what brand and size front tires were on the CCW & ZO6 rims? Also, were the ZO6 rims factory OEM 17x9.5 or aftermarket 17x9.5?

Vince98

Picked these up yesterday 17x5 & 17x11s 295/45/17 et streets on the rear. Can't wait to get them on the car. I'm thinking about having the polished lip powder coated black though.

Redvette_22

What model Vette do you have....GS/ZO6/base??

Vince98

It's just a old 98 base coupe man nothing special.

Chris Stewart

That was CCW 16's with Firestone Champion compared to OEM Speedlines with F1 Supercar tires.
