Got some Nitto 305/35-19 NT05R's and now encountering massive wheel hop from 1st-3rd gears (MT82). The absolute best pass I could get was a 13.01 @ 114 mph w/ a 2.32 60ft (1/8 mile = 8.70 @ 88.26 mph). 3000rpm launches had killer hook, rolled out pass the beam and hoppity hop. Back off the throttle, back on, shifted to 2nd, bit, rolled a little then Hoppity hop and so on. Tried different tire pressures, lower = worse higher = better ( to a point ) Previous Bias Plys had zero hop. :frusty: Pre Drag Radial I've gotten away with not using a cradle lockout kit, but now I'm guessing I need one? :shrug: Or is there something else amiss here? Thank you.

I've never done anything but break stuff with radials on my stick car. Get something bias ply and use that at the track. It well make a huge difference in performance and wheel hop.

Double adjustable shocks help, plus all the usual things locking everything down, but the problem is drag radials like to be dead hooked, they don’t like wheelspeed, and a stick car needs wheelspeed. Drag radials are rough.

Yeah.. the 35 aspect ratio doesn't help. Thought lowering the tire pressure to 18.5 psi would help.. made it way worse. Had to cut the run short and did a 14.08 @ 65ish mph lol.

I had violent wheel hop and what really fixed it for me was bmr lowering spring, bmr vertical links and bmr cradle lockouts. I changed my tires from the stock Pirellis to mpss and it was worse the next time I took it to the track until i did suspension.

what suspension/cradle mods do you have on the rear? on stock everything i would get some pretty bad wheelhop trying to launch even on the stock pirellis on 1st/2nd depending on how i shifted.

ive got lowering springs & bmr cb005 now but haven't gone to the track yet as i am in need of new tires, lol.

Try the Steeda IRS support brace. Easy install, no alignment needed, inexpensive, and works great!

[MENTION=7748]tj@steeda[/MENTION].. would love too, but your shipping to Canada is ridiculous, and steeda.ca (your Canadian distributor) charges ridiculous prices + it's a crapshoot on when you'll actually get ur parts in a reasonable amount of time.

I have literally ALL the parts and NOTHING stops the hop completely on a radial. Bisa plies are bliss.
