1500 street miles, 30 auto-x runs on concrete, 60 runs on typical asphalt, and a handful of mountain runs.

Front:


Rear:



I ended up watering them down at Blytheville.... 95+ degrees, concrete, two driver car. They seemed to have more grip and posted faster times, mind you we only had 3 runs each day so that's all relative. I think during hot days I might prefer the RS3s, I really want to do a back-to-back test of them on my car.

I figure they would make an awesome HPDE dual purpose tire.

ok, sorry for the slow response but we broke the transmission last event so we didn't get to do the comparison between the rs3s and rivals till yesterday.
rs3s are faster in the florida heat for sure. dad and I both improved by .5 from the first 3 runs on rivals to the the last 3 on rs3s.
now if its cold or you don't have a codriver maybe the rivals are as good. but a 2 driver car in the florida summer the hankooks are faster

What was the weather like? Do you think some of the improved time was from learning the course? Or were the RS3s just grippier?

it was over 100 degrees that day. im sure when its that hot the rs3 is faster.
if it ever cools off I bet the rival will be better. it seems to have decent grip without any heat in it

Yeah they perform very well in autocross during cooler temperatures. At the beginning of the year I couldn't get enough heat in the RS3s, I was getting pretty frustrated, after I switched to the Rivals they grip after a couple turns.

On a lemons car in hotter weather on the track they do seem to lose time after a few laps, nothing drastic but noticeable. The fastest lap times drivers were set on the 2nd lap or right after a long caution. Those are the only tires we ran on the car so can't really compare them to RS3s. This is on a camber challenged E30.

Maybe the gun turret was weighing you down?

Haha, it's pretty lightweight. The US Army has inquired us about our superior turret design, they were very interested in the space age materials we used to keep it light (cardboard and aluminum).

Corrugated paper sounds much more scientific.

Well the latest GRM has the RE11a, Rivals, Z2, and RS3, and an 8 vs 9 wheel comparison at Harris Hill raceway with a K24 CRX. Interesting read.

205 vs 225 Rival on an 8" the lap times were very similar. The z2 tested 1 second slower on a 83 second lap. A 9" wheel gained half a second. The RS3 was beat 4/10ths on average and 6/10th on the best lap, which it said was made under trailbraking and power on corner exit. This is in a 250+hp FWD car.

Biggest surprise to me was the Z2 times, although I'm taking those with a grain of salt. If you guys remember the first review before autocross season it tested the rivals vs the magical 195 r1r, and the rivals won. And then you look at the SCCA national results



BFG is one of the sponsors for SCCA, a review with the Rivals beating the r1r was pretty convenient at the start of the season when everyone is ordering tires.

To be fair, the rival is a good tire at sites that arent Lincoln. It is an awful tire at Lincoln. Its so bad to the point that if I was running an ST class I would run rivals everywhere else and have a set of anything else to run at lincoln.

I like it a lot more on FWD then I do on RWD though. They feel like a worn out set of slicks. Which means with RWD they're trying to kill you constantly but with fwd they're awesome. That could be the setup of the miata I drove them on though, it was running xidas with sub 4" ride heights with reverse rake and did feel like it only tried to kill me when I felt the rear bump stops engaged.

Any chance you can hook us up with a non-Facebook link? I tried a quick Google search but no luck.

Edit: Is it this one with Hot Rod?


ZII with the quickest time and the NT05 at the bottom?

I think this is from rubbing the shock tower. I'm not that low, 4.25"/4.5", didnt really have this issue with the rs3s. Maybe the bfgs are just wider than the rs3s?

Anyways, I need to figure out how to remedy this issue. First thing that comes to mind is raising my front end some. I'm not sure how much I'll need to raise it and I'd hate to get it set, aligned, and then still have the same thing happen. I also figure this is a common thing with 15x9s, 225s, and low cars. Does anyone have any experience with this?

What wheels and what offset? I rubbed exactly like that with the 275hohos on the 15x9 6uls unless I put a 6mm spacer. But those tires shouldnt be wide enough for that. I did see an NB running these tires on 6uls with xidas do this exact same thing to the drivers side front, he said it was brake lock up, but brake lock, does not wear the tire all the way around.
