Thanks Rick. Is there any aftermarket wheels that I can run this tire size without any spacers or is the setup you use the current best bet?

If you want rotatable wheels like I'm using spacers will be needed. Stock or R CF wheels will work fine. The N4SM R spec wheels are also available but they have very tight caliper clearance for track use. Then there are custom wheels but the price goes way up.

Tight to the calipers , actually causing any problems, or just close like a lot of rims are on many of these new cars with huge rotors?

Not really true, I usually se a 30 degree spread across the face of the tire that is handling at it's optimum

Higher temps on the outside? I don't check temps very often as I'm not keeping lap times plus I'm kinda lazy. :blacksheep-1 said:
I'm more concerned about wearing evenly.Another thing to consider about using the CC plates is steering feel. More camber typically sharpens up the steering and I can tell the difference on track and unfortunately on the street too.
Hi guys, my r spec wheels are almost here and its almost time to buy some track tires. I've been reading over the numerous tires post but was still hoping for some advice, hope its ok to ask here as I didn't want to start another post.
Here are a few facts that may impact your recommendations.
1. I decided to go 305/30/19 all around
2. I will be setting the front camber to 1.8 as I will not be adjusting camber settings between track and street.
3. I do not compete in timed trials, so I don't want the most expensive tires, however I still want improved grip over the PSS as I found them to get greasy quickly.
4. I do 3 track(lapping) days a season, and a typical track day consists of 6-8 (7 minute ) sessions, so a lot of heat cycling I believe.
5. I need to drive about 100kms to get to the track, so full slicks are out.
I have been going back and forth trying to decide between the RE71 and the MSP2, with leaning towards the RE71 mostly due to cost here in Canada. But just yesterday the Trofeo R caught my attention, as I found a local deal on them thats less than $100 difference more for the set than the RE71s, and $500 less than the MPSC2s. Kind of want to give the Trofeos a try since the deal may not last and they always been out of my price range.
What do you guys think? Sorry for the long question, maybe I should have made a new post. All input greatly appreciated, Thank you.

@TRAC WPN welcome to TMO. If you can wait a bit longer the new Michelin PS4S should be out soon and it's another tire to consider. I suspect you need a tire that works in the wet but if not also consider the Nitto NT01.

Both TRAC WPN and TRAK WPN plates were taken here in California so I had to get creative. ;D

@voodooboss thanks for the welcome, I was lucky here in Ontario TRAC WPN was open. I don't care about wet performance as I only track on nice days, and if I get caught in the rain I will manage to get home. I will stick to the pss for street use. I heard about the ps4, but I doubt they will equal on track performance of the RE71, I may be wrong tough.

If that's a 7 minute session every 45 minutes to an hour, then something isn't quite making sense to me. When I go out, by the time I'm at seven minutes, I'm on my third lap of a 20 minute session and the brakes and tires are nicely warmed up and I'm getting solid performance. What I'm hearing from you is that by seven minutes, your tires are overheated and losing grip. I didn't think the MPSS's were that sensitive to heat. What am I missing? Is this more like an autocross course with lots of tight turns linked by short straights? For sure that'll heat the tires up fast. Brakes too. If that's the type of driving you're doing, then you really need a good autocross tire.
That said, if I could get Trofeo R's for less than the US-made Sport Cups, I'd just buy them. They are great tires. You have to manage the pressures, though. They're designed to run 29PSI hot.

Yes the track is not very tire and brake friendly. A big section, like close to half of the track is very tight, comparable to auto cross. This section is done 95% in second gear. But to be fair to the pss tires, I definitely over drove them in my RCF. Next time around I will be a lot smoother and gentle through that section, and try to have more fun through the faster part of the track.
Picked up the Trofeos today, at $363CAD each I had to give them a try, will report after I try them out on the track
Hopefully will try them out this Sunday, and report back
Using the project 6 gr wheels in R specs, love the look and price
So I went to the track for the first time with my GT350. I just want to first say that I do not have a reference point tire wise on the GT350, as well as I don't own a tire temp. probe, so my tire impressions are what they are.
Tires used 4 X 305/30/19 Trofeo R mounted on project 6 GR in R specs.
Started 28PSI cold, and felt a littles slippery first 1.5-2 laps (3kms/lap). The tires build up some pressure and they stick. On my home track (Toronto Motorsport) very tight and not tire friendly track, I found the Trofeos worked best at a 31-33psi Hot range. At 30psi and 34psi there is a small drop off in grip, at 35-36psi the slip was much more pronounced. Adjusted the pressures and all is well again. Found the steering to be very good and predictable, the nannies kicked in a few times when the PSI built up past the 30-34 range, but I admit my throttle application was mostly to blame. Camber settings were -1.8 front and -1.45 rear, and the tire wear wasn't too bad on the outside of the tires. Possibly they could use a bit more - camber, but I don't change my settings between the track/street, so happy with what it is.
Thats about it, like I said these will become my point of reference, once they wear out I will probably try the RE71Rs, unless I can find a set of Trofeos/Sport cups2 for the same price.
Just to add, the GT350 is by far the best car I took to the track(RCF,S2000) were the previous ones. The only upgrades I may consider in the future may be the R springs, not to say the stock ones felt weak.

Thanks for the review. The Trefeo R and PSC2's should be two of the best tires for the car if you are driving to and from the track. @Black Boss has posted that the PSC2's are close to the Hoosier R7's. I might try the Trefeo R for my next set of tires but if the PSC2's are still on sale I will buy another set of the Michelin's.
Great read and helpful. I'm new to the Ford, in fact it's still pending delivery (GT350R) and shows only one more
Day on Ford website... I picked up some 6G R-specs as well and need to mount some good track tires.
Reference I've had 7GT3 (NTs, slicks), Radical (slicks), 6TT NTs and am wondering how the PS2cups compare against NTs. People love the NTs, but after slicks- even used its hard to fall back in love with NTs.
Hoosiers are ~$2k, while PSC2s are 1500. Are they better than NTs?
