Julian H Posted February 28, 2015 Share Posted February 28, 2015 HiI currently use 13" CR500s. Assuming I need to change to ZZS [for on road], and a second set of wheels with ZZR for track, am I going to need to change my front wingstays?My current 175 fronts [on 6" anthracite 8 spoke wheels] are only around 8.5mm away.

Grubbster Posted February 28, 2015 Share Posted February 28, 2015 I've just replaced my wing stays (removed custom cut and welded ones) with race ones and can confirm that the 185/55 R13 ZZRs fit ok - I just fitted a wheel to be sure. Link to comment Share on other sites More sharing options...
Julian H Posted February 28, 2015 Author Share Posted February 28, 2015 Hi GrubbsterThanks. Do you know, is that what CC are fitting as standard now? How do the race wingstays differ to normal. Appearance, finish etc? Can I use my existing CC CF wings?Cheers Link to comment Share on other sites More sharing options...
Grubbster Posted February 28, 2015 Share Posted February 28, 2015 Standard wings will be fine. The race wings don't have the facility to thread a side repeater wire down the tube (there's no hole for it to come out through) and I think they are slightly lower than normal but I don't have any to compare with (so possibly not able to clear a taller tyre like the Academy CR322s). Other than that they look just the same, satin black, they fit the same. To the untrained eye I expect they'd look identical.I found that the standard wingstays put the wing quite a long way from the tyre with a CR500 - too big a gap. So I had mine 'cut and shut' so they site snugly around a CR500 but they couldn't then take a ZZR! So I've just gone to race stays which will take either tyre and hopefully won't sit as high as the standard ones do.So the much shorter answer to your question is that if you have standard or race wing stays and standard wings then you'll be able to fit the 185/55 R13 ZZRs.

Julian H Posted March 3, 2015 Author Share Posted March 3, 2015 Hi, thanks...So, the new tyre is 12mm wider which means it will sit closer to the wingstay by 6mm? So will I really end up with 2.5mm clearance? Or what am I missing here? Link to comment Share on other sites More sharing options...
Grubbster Posted March 4, 2015 Share Posted March 4, 2015 I'm not home till tomorrow but I can measure the gap on my car for you, it's more than a couple of mm from what I remember. Link to comment Share on other sites More sharing options...
Julian H Posted March 4, 2015 Author Share Posted March 4, 2015 Great thanks. Let me know.In the meantime I have ordered my new wheels [CC new style black/diamond cut] and now BMTR are out of ZZS until nexr week . Link to comment Share on other sites More sharing options...
Julian H Posted March 4, 2015 Author Share Posted March 4, 2015 HiJust a thought, what wheels do you have? If the offset is greater than CC standard [ET24?] that may be why you dont have a problem?Cheers,J Link to comment Share on other sites More sharing options...
Grubbster Posted March 4, 2015 Share Posted March 4, 2015 I'm just on the CC anthracites, nothing unusual. Link to comment Share on other sites More sharing options...

AdC Posted March 4, 2015 Share Posted March 4, 2015 Hi Julian, sorry to be off topic but if you're getting ZZS's and have the opportunity to weigh them before fitting I'd be interested to know the result. My recent ZZR's were heavier than I thought (I'm led to believe the design was beefed up last year) so I'm curious about the ZZS's. Thanks.

Julian H Posted March 5, 2015 Author Share Posted March 5, 2015 Hi Yes sure. I can weigh them on the post room scales at the office I hope the ZZS are not too heavy. I wonder if I should be sticking with CR500's for longer if they are? Link to comment Share on other sites More sharing options...
Grubbster Posted March 5, 2015 Share Posted March 5, 2015 Just got my feeler gauges out to measure the gap, at the closest point (the rear stay) there is 5.1mm clearance on mine, I'll stick some photos up later. I never weighed the ZZRs but when loading them into my boot they did feel noticeably heavier than the CR500s that I loaded at the same time.

AdC Posted March 6, 2015 Share Posted March 6, 2015 Thanks Julian. My brand new 2015 ZZR 215 13's weighed 9.35kg and the 185's weighed 7.65kg. Link to comment Share on other sites More sharing options...
Julian H Posted March 7, 2015 Author Share Posted March 7, 2015 Morning gents.5.1mm away sounds okay. I wonder if my wingstays have been fitted incorrectly since logic tells me, mine would be closer with ZZx. I'll have a post-blat look later this morning. Regarding the weight thing, I am a little unsure what to do. If I can still get CR500 I think I should? Was thinking later designed ZZS should be better but if they are heavier I'm not so sure. It's daft, CC proclaim new lighter wheel for 2014 (the Apollo) but then we fit heavier tyres J Link to comment Share on other sites More sharing options...
AdC Posted March 7, 2015 Share Posted March 7, 2015 Cards on the table J, I probably bought ZZR's because they looked "racecar!" as much as anything else, and wonder if I'd notice if they were each a kg lighter, such is my ability. Whatever you choose, they're consumables so you'll get another go at some point. Link to comment Share on other sites More sharing options...
Julian H Posted March 7, 2015 Author Share Posted March 7, 2015 HiThis morning I nipped down to CC (main reason was to take back a flawed diamond cut Apollo wheel ) and had a good look at several cars running ZZR (same profile as ZZS) and a chat with eternally helpful Dominic. We had a look at wingstays together, including my own, and established I am not going to have a problem. Also, I had a chance to look at both ZZS and CR500 fronts. Conclusion, the ZZS are slightly heavier. But they look so good like you say, so will get a set when they are available J Link to comment Share on other sites More sharing options...
