800whp ess a10 car with magneride. needing some advice to help with getting traction.

have full stop the hop stuff, dual rate springs, diff inserts, and nt555r2 tires. 4th gear is fine but 2nd and 3rd i blow the tires off. granted the tires are getting close to being done and i have a new set in the garage. just trying to be proactive and get some advice for either different parts or different tires.

i realize having dual rate springs and magneride is not ideal for doing pulls at this power but i dont really want to change that out due to the fact i do enjoy putting my other tires on to go around corners and to the road course. i understand that i cant have a jack of all trades here without sacraficing something but i just want to do all that i can to get as much grip as i can.

thanks guys

I think you’re gonna need a set of play shoes (sticky tires) and a set of dress shoes (cruising/corner carving tires) depending on how you’re using the car.
i have that currently. i have the r2 tires for straights and i have a pretty set with some ps4s

305 45 17 et street R Hook up nice in third gear with that power. Also what rear gear is in the car? 3.55 will hit hard in second and blow the tires off.

i was thinking this but i dont know if et street r is "safe enough" on the street vs the et street ss. but then again idk if the ss would hold he power.

i do mostly roll racing so the speed will get pretty high. ive heard horror stories about the sidewalls blowing out if your at high speeds for too long so im a little worried about that.

plus i also hear that you have to be very careful when taking any corner on the r but the ss has a little bit of forgiveness

yea im a 3.55 car never tried 2nd gear at all due to the fact if im spinning in 3rd already then whats the point going into second 😂

I ran the Mickey Thompson 305/45-17 ET Street R (radial) on my 2019. I’ve even driven on the highway with them several times without issue. I would only do this on a radial (not the bias ply version) though. I’ve gotten caught in the rain on them once and it was not a fun experience at all. The SS might be more forgiving in rain.

To be frank, your typical modified street car went from 500 rwhp to 800 rwhp in 20 years but the tire technology hasn't appreciably changed or even remotely kept up with the increase in power.

I've run NT555R2 and ET Street R, and my friend has also run R2 and ET Street SS. Here are some notes we've both experienced.

The NT555R2 is a really great all-around street tire. It handles well, wears well, takes some wet roads reasonably well, balances out easily, doesn't feather up, etc. All-in-all a good tire, but in ideal straight-line conditions it will not get the traction that an ET Street gets.

The ET Street SS and R have the same compound (ironically, it's called "R2" by MT) but different construction and tread pattern. All-in-all the ET Street tires pretty much just suck in every category except ideal-condition straight-line performance, and they're only good in that instance if they haven't feathered up yet. My buddy struggled to get his SS tires balanced and ultimately never could get them to balance out. My R's balanced "ok" but they flat spot. They run rough for a mile or two after letting the car sit at all. Maybe it's placebo but the R's seem noisier to me as well. Of course, they are terrible in the rain, and sway in the curves. If you don't treat them just so, they feather up and are basically ruined from that point on. They sacrifice a whole lot to get a short-lived edge in straight line acceleration. But if that’s your priority….maybe it’s worth it.

I'm about to switch back from a 305/45R18 ET Street R to the NT555R2 to see how they work in this particular size. If they're unacceptable, I'll wind up back with ET Street R's on a dedicated set of track wheels and just give up on great street traction.

My car is a manual and I’ve gone 1.7 sixty foot times on my Mickey’s with 639 rwhp/602 rwtq.

I’ve also gone 1.7’s on a Hoosier QTP bias ply which is what I have on there now.

I think the 10R80’s 1st gear is like a 4.70, which is why it’s spinning so much on takeoff.

thank you for the incredible details youve given. i still have a new set of 555r2 to put on so it gives me some time to figure out what to do next. im trying to ask around for people that have similar power and usecase to see what i should go with. these will be definitely an option to consider
