Guest Thurem Posted November 27, 2001 Share Posted November 27, 2001 Just saw the adaptors you offer, to install fwd type wheels on the Z, looks like a good deal. It made me think though. How about making a bolt-on 5 lug adaptor with an integral hat for the brakedisc, ie. an 8 bolt hat for Wilwoods. Then we could convert the front with a 84 turbo hub, and the rear with your adaptor, this way we could use the same wheels front and rear + combined with coilovers fit large wheels and trick brakes. Obviously I have no idea how hard or easy this would be to manufacture. Thure Quote Link to comment Share on other sites More sharing options...
Modern Motorsports Ltd Posted November 27, 2001 Share Posted November 27, 2001 " How about making a bolt-on 5 lug adaptor with an integral hat for the brakedisc, ie. an 8 bolt hat for Wilwoods." I'm not a big fan of wilwood or others fairly affordable stockcar type calipers. I much prefer those with outer dust seals, of DOT origin (whether brembo/PBR or 240sx etc), and if possible to retain ebrake out back which my customers have continuously requested. I try and stay with parts easily replaceable and available. I don't typically tech/go through my car a few weeks in advance of an event. It's generally the week or two ahead in which I go hard at it, going thru all systems etc and if I might have any needs I want to be able to get them quickly. Then again that's why I built my front 13" setup healthily above min. spec so servicing/parts would be greatly minimized. "Then we could convert the front with a 84 turbo hub, and the rear with your adaptor, this way we could use the same wheels front and rear + combined with coilovers fit large wheels and trick brakes." Well front and rear on Z's for max tire/rim aren't symmetrical in my experience. So even if I made a front and rear (swap to 5lug) package with identical offset from OEM offset, their would be buyers still wanting to stagger their wheels differently to make the most of their fenderwells whether they had flairs or not. I'd like to avoid seeing anyone 'stackup' spacers, ie. use a 4 to 5lug bolt on and then shim it out further.......I prefer a single spacer of exact thickness required ( not much public info on spacer requirements with 5lug setups on Z's) It seems quite rare that any three or more guys run the same thickness spacer/wheels/tires etc. The 4 to 5 lug bolt on adaptor for the rears I have fully designed and it might see production early spring. RIght now I'm fully concentrating on seeing my two CNC projects underway to production. FWIW, the rear disks are in the machine shop queueue and the prototype pair is supposed to be made at the end of this week. Then a check to see if geometry is ideal, revise anything needing a touch up and they'll see production. Personally I think 11-3/8's brembo disks paired with suitable pads should satisify most all Z rear braking needs, but that's flexible as the customer is always right I've had a few 13" rear disk requests but once we covered over some general braking requirements they decided it was overkill and unneccessary. I still might do something like that on mine at some point but it's a ways off. On your same note the 4 to 5 lug bolt on adaptor when used out back, does not alter the brake setup at all if it's only for a lug pattern change (ie. bolt on over the rear brake disk).

CruxGNZ Posted December 3, 2001 Share Posted December 3, 2001 Ross, could your adaptors to go from 4 to 5 lug, be used for high horse power/high torque cars? I'm not sure about any kind of adaptors yet. Are adaptors for FWD wheels and the proposed 4 to 5 lug adaptor suitable for most any kind of vehicle? !M!

Yes Mat they could. I don't sell/make anything designed for moderate power levels. Parts I have an influence on I make damn strong so it's not the weak link. Its not worth it at ALL to only build it 'moderately'. Liability/stress could in no way make up for any cost/design savings for myself. I'm a prof. engineer by career and public safety is just ingrained in myself. Having said that, all aftermarket products are typically for you to determine their suitability of function for your application with generally no guarantee of function for a particular purpose. I've seen this written in countless places and it's echoed on the bottom of most every invoice of any of my suppliers whether import parts or stock car parts. As I understand it, it's economically unfeasible for all these products to be DOT tested both on their own and for install methods. If their was enough public outcry for DOT testing etc then I'd venture a large part of the aftermarket couldn't even dream of offering products including several of us involved with this forum. Testing to those levels is very pricey and would sink most of our business plans in a wink. Sorry to babble on... Yup, my wheel adaptors will be strong and available Quote Link to comment Share on other sites More sharing options...
DavyZ Posted December 9, 2001 Share Posted December 9, 2001 Just to offer some additional opinion, I have seen these adapters first hand and I can tell you that they are strong looking! As of now I don't need any adapters, but if I change wheels and need them, I'll NOT think twice about using them. Just my $.02. Davy Quote Link to comment Share on other sites More sharing options...
