Looks like Tire Rack added the SP Super Sport Race to their lineup. Very reasonably priced too.

Viken-do you have Dunlops on yours and if so how they compare to Pilot Sport Cups? Regards. Mike

Viken

No, I don't have them. However, Lynn has used them on his GT3 and liked them a lot. I also had the chance to drive them on a friend's GT3 at the track. They are really good in the dry, and are supposed to be better than other R-compounds in the wet. My feeling is that the Dunlop's dry performance falls between a good maximum performance street tire and the Michelin Pilot Sport Cup. It has a softer sidewall than the MPSC, and might give a better ride on the street.

I am pretty sure those who have tried the SP Sports would chime in here.

No 295s yet, but the 285s are as wide as most 295s. I prefer that tire to the Corsa.

I just ordered a set today to use as intermediate rains. We'll see how they work out. Don't expect them to be as good as a Hoosier or Hoosier rain, but I want something I can use in damp/rain/drying conditions without them overheating like the Hoosier rains do. I used the Kuhmo's in the past, but find them very unstable over 130 mph.

Excellent price! I had these tires before on my BMW M Coupe, very good grip in the dry.

Viken: Are you calling me?

The Dunlops are much better than the stock tires, but don't stick nearly as well as the Cups in the dry. Haven't used the SSR's in the wet, but their tread configuratuion should make them better than the Cups in the wet. As Viken mentioned, the Dunlops seem to ride better (i.e., less harsh) than the Cups on the street. FWIW, that's my take having experienced both tires on the GT3. Also, the Dunlops wear well.

The Dunlop is 1.0-1.5 seconds per lap slower at Summit point than the MPSC. The lap with the Dunlop in the GT3 strret car in stock trim at stock height with -2.0 camber is 1:23 with either myself or Keith alexander driving. We were both on the Dunlop at the recent PCA club race with consistent times in the 1:23s during the sprint race. These tires, at least in my case, had a couple thousand street miles and a handful of track days prior to the club race weekend. The tires are very progressive at the limit; moreso than the MPSC, but the cups are quicker for an ultimate flyer lap.
At the lime rock club race, I will be doing a test with Dunlop engineers on the SP tire, but shaved to 4/32. We think this may be as quick at the MPSC-or at least very close.

The Dunlop is drivable in the rain as was evidenced in the wet practice session at the summit PCA race. It is excellent on the street and a terrific all around tire with absolutely remarkable longevity and price value.

I will be iusing the MPSC for the DE day prior to the PCA LRP race in 2 weeks and then will switch to the shaved Dunlop SP tire after the first practice for a direct lap time comparison. The car will be stock with a lowered height and relatively aggressive camber but will be equal from tire to tire.

Considering the differences in the cars and tires, the car was relatively close to the cup cars in lap times during the race. Keith and I both drove our cars to the track from NY and back home on the Dunlops we raced on, which was over a 6 hr trip each way.

But they dont make them in our size!!!

Anyone know how they compare to the Corsa R, the Dry weather Corsa's??

Regarding the GT3, use 245/285 Dunlop SP. It is nearly identicle to 235/295 MPSC in size.

cosmos

So I am going one size larger in front and one size smaller in rear, BUT these Dunlops are the correct size to install on the stock size wheels??

I am just confirming before I order from TR, I am getting 245/??/18 AND 285/30/18??

Will changing to these sizes effect handling, such as creating more understeer??

Thanks,

ldw

I can't make formal recommendations, but i can say that the Dunlop 285 and the 245 are very close in dimensions to the MPSC. There have been no issues with rubbing nor handling with these sizes at stock or slightly lowered ride heights in my experience. A 245 at one tire manufacturer often is not the same as 245 at another. One must actually measure the tires together mounted and inflated to compare. New handling conditions can be managed with sway bar adjustments.
They have mounted fine and fit well without issue on my stock wheels.

Got them,

However the 235 and 285 Dunlops were the closest to the 245 and 295 of teh MPSC tires.

Goes as follows:
MPSC 245/40/18 = 25.4
Dunlop 235/40/18 = 25.2

MPSC 295/30/18 = 25.2
Dunlop 285/30/18 = 25.0

So, thats that, for the price WOW can't be beat. $600 for all four deliverd to my door.

So what Dunlop size should be used for the front- 235 or 245? Regards. Mike
