http://www.camaro6.com/forums/showthread.php?t=487124 In an ideal world I would love to do an 18" track wheel but I think glamcem had a tough time fitting it without doing a lot of grinding. I think what you'll find is that a lot of us won't mind running a spacer up front to run a square setup on track. I'm currently running a 5mm spacer up front with your 19x10 et25 spec wheels for clearance although now that I have camber plates I could probably get away without running it. I even think a number of us would be OK grinding our strut a little bit for clearance as glamcem did. An 11" front wheel will would be ideal with the ZL1 but on a regular SS the 11" wheel sticks out to far IMHO and I know a 305 will fit on a 10.5" wheel. It may not be ideal but I don't think I've heard of any performance disadvantage. I could be wrong however. In the end, I'll leave it to you guys to decide what's best but I definitely think that if you can come up with a square setup of 18" and/or 19" that allows for the use of a 305/30 on all 4 corners it will sell, even if you have to put a disclaimer that "some grinding and a spacer may need to be used up from on MRC equipped cars." I have camber plates which gives me even more flexibility when it comes to front widths because I can put more camber at the plate and less at the knuckle which will help a ton for wheel clearance at the strut. I can run something like .7 degrees at the knuckle and the rest at the plate rather than having to run all -2.7 degrees at the knuckle. Thank you all and I look forward to seeing what you come up with. Any chance there will be a first run group buy? |

Unfortunately, running a square setup is not an easy task for 10.5" or 11 wheels up front without having too much poke in the rear and/or having some grinding, 10-15 mm spacer and of course longer wheel studs because of the thick spacers up front.
Another option is to get some camber plates but I'm personally not a big fan of them and not sure how many people would be willing to install them (especially after hearing the failures). It still won't address the issue of having the offset delta between front and rear by the way. You can of course run 19x10" or 18x10" wheels but it would be a downgrade at the road course track all things being equal (running used slicks or R7s is not everyone's cup of coffee) Also ZL1 1LE specific wheel specs will only work on ZL1 1LE (duh) and probably the previous Gen Z28 as they both had Multimatics and fender clearance. Although the rear fitment will be fine, the front will rub (Sean used them at the Laguna Seca) and some spacers will be required to be able to run more than -2.5 camber. ZL1 owners have the wider fenders but they still have the same struts so inner clearance issue will still be there. For the reference, going from 10" with +20mm offset to 11" with +11 mm offset will move the tires 22mm further out and result in 4mm less clearance inside which will probably be an issue with aggressive camber. I think the most ideal setup for a broader audience would be something like : 19x10.5" +14 (same inner clerance, 12mm furher out) offset for the front for clerance and camber and 19x11.5" +37mm offset (same inner clerance, 12mm further out) so the overall track width for both front and rear would remain the same. Having 19x12" with around +35-40mm would still work for the rear For the 18" wheels (SS and SS 1LE owners only as the front wheels won't clear those ZL1,ZL1 1LE or Gen 5 Z28) brakes: 18x10.5" +12mm (because of the tighter fitment due to knuckle) 18x11" +43 or +44mm ( Already offered with FL-5, SM 10 and EC-7 models) for the rear I was running 325s on 11" with no issue as it's within the recommended range and since 335 or 345 may be not be that necessary since we don't have the power of the ZL1 cars I hope that helps

Survey done!
Just wanted to mention that Anderson's Composites has new front fenders this month that are .4" wider than stock fyi (woohoo!)

My rears have 18mm poke and even with the 325s I don't deal with any rubbing so 12mm poke should be even better with -1.6 camber. Front poke is not noticeable at all in my case. I have only about 9mm poke with 19x10.5" +17mm offset (+22mm with 5 mm spacer) additional 3mm poke shouldn't hurt anything

maybe a 19x10.5 +30 for square? That would be good in the rear and if I add an 8-10mm spacer up front the front fitment would be pretty good too That is just my wishlist of course Last edited by Eric SS; 11-14-2017 at 06:06 PM. |

However, after trying 325s in the rear, I noticed how much grip I was leaving on the table with 305s. In other words, going with narrower wheels is very counterproductive IMO. Have you ever considered rotating tires on each side and have a tire shop swap front with rears after say 3-4 events ? If your ultimate goal is to run same size tires (305/30/19), it may be a good alternative to sacrifing the rear grip or not being able to run/test wider tires in future. Yes it will probably add additional $50-60 bucks between tire changes but it will also allow you to try other tires such as 295-315 R7s, 305/ SQ, 305/315, 305/325 ..etc Just a thought..

FWIW this is what 18x10.5 +22 fitment looks like.
There's good caliper clearance for the 1LE 6 piston calipers. It JUST clears the strut with a 10mm spacer. This is with no grinding and -2.6 degrees camber. Less than 1mm clearance. Fender clearance looks ok. Rear pokes out just a tad, not bad and might tuck under with compression. This is at -1.6 camber. They are good looking wheels!

18" wheels/tires would be game changer for sure
Quick comparison : OEM wheels/tires weigh about 60 lbs on each corner 18 " Apex SM10 wheels and R7 tires about 45 lbs!! ( That's a total of 15 lbs difference on each corner and total of 60lbs rotational weight reduction. For the reference, that is the difference puts the GT350R apart from the GT350 with its carbon fiber wheels. For track use, I cannot think of a better improvement for the money
