Whats up guys, I have a Drag Radial question. Basically im looking for the quickest drag radial for my C5Z. My car is a coilover suspension Built forged N/A LS7 making 600/575 through a RPM Stage VI 4L65 "Trans Brake/3200 stall" and a Built RPM 3.42 C6Z diff. The car is primarily a street car with the occasional trips to the track. Im torn between just leaving the 18's out back and going with a 305/35/18 ET Street or picking up another set of 17's for the back. If I go that route I am conflicted on tire heights and pros and cons. I love the look of a 27" "295/45/17" tire because if fill the wheel well nicely but I am afraid it will actually make my car slower then what its capable of with a shorter tire. I think that a "275/40/17" is too small which is in the range of 25.X"... Does anyone know the height of say a "305/35/17"? I know a 305/35/18 is 26"...

Any advice or info on the subject would be appreciated.

My brother runs the toyo r888s in his heads/cam spray c5z and he loves them.

R888's are not a Drag radial. They are Road Racing tire, It may work for him but that's what they are meant for, Not drag racing...

They work on a car that makes 690rwhp with a stick.... The side wall is hard, but the center is soft like a drag radial.

I understand that but Its not what im looking for... It may have a hard sidewall and soft tread compound but its not a DR. The height on the tire is to short. More comparable to a normal street tire in height...

Nt05rs work great on my car, could also get the Mickey thompson et street II, I've heard they work great too.

I run mickey Thompson 305 35 18 drag radials on my car. On stock suspension and from 40 and on a concrete road they hook 735 rwtq. I had nittos before this and they were good to about 500 rwtq.

Yea I may just do this. I had the same tires on my other Z06 making mid 400whp and they were so so... Tires were probably just old though....

I have Hoosiers but they're small, 26". I've had 555Rs and god they suck. I'm hoping with the auto I can rip sub 1.55x sixties with the Hoosiers. If not I'll be going up to 28" on 17s.

im running 315/30/18 hoosiers. the car is a th400 5500 rpm stall. I can hook a low first gear roll on 10 psi boost without any burnout as long as its 55 degrees or better out.

MT 305/35/18 but you might break something i run em at 16 psi

yea 555R's suck *****, You will have no problem pulling 1.5X 60' times with a 26" Hoosier. I was running 26" Hoosiers before and was pulling 1.49-1.51's with my Auto.... Only reason im getting away from the Hoosier is because I want to leave a tire on for the street as well and the Hoosiers waste away quick on the street and pick up everything...

Nice

Im not breaking anything. I have a full built suspension and RPM built C6Z diff...

Do a 15" spindle swap and add a 275 pro drag radial..call it done

Weld rts 17' and M&H 325/45/17 hook pretty good 1.40 60 foot
