Guest zcarbum Posted November 10, 2002 Share Posted November 10, 2002 wondering if those of you with autocross expierence, can inlighten me on my question!! "can you use spacers on a 280z (hub adaptor 35-40mm) to autocross with out having negative effects to handling, or hub problem????? thinking of using "Modern Moto"'s wheel hub adaptors for my 76.. So i can get the wheels i want..but I may try my hand at racing this next year...what do you guys think?? -------------------------------------------------------------------------------- Posts: 1 | From: Oregon | Registered: Nov 2002 | IP: Logged | Quote Link to comment Share on other sites More sharing options...
johnc Posted November 10, 2002 Share Posted November 10, 2002 A 1/4" spacer on the front can help reduce understeer with 7" wide wheels IF everything else on the car has been setup correctly for autocross. Otherwise, it just adds weight. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted November 21, 2002 Share Posted November 21, 2002 for Serious autocrossing I don't recommend it.there is enough stress on the front wheel bearings already. Quote Link to comment Share on other sites More sharing options...
johnc Posted November 22, 2002 Share Posted November 22, 2002 Lots of guys run wheel spacers in front when autocrossing and running in ITS with 7" wide wheels. It gives you a wider track and reduces understeer. Wheel bearings and spindles last just fine with proper maintenance and regular replacement - which you should do on any race car.

Dan Baldwin Posted November 22, 2002 Share Posted November 22, 2002 I'm pretty sure increasing front track will INcrease understeer, as it increases the lateral load transfer at the front relative to the rear. In any case, I think zcarbum wants to use spacers to fit fwd-offset wheels, not necessarily to increase front track. Quote Link to comment Share on other sites More sharing options...
Mudge Posted November 22, 2002 Share Posted November 22, 2002 I'm pretty darn sure increased track in front would reduce understeer. Quote Link to comment Share on other sites More sharing options...
Dan Baldwin Posted November 22, 2002 Share Posted November 22, 2002 Well I'm pretty DANG sure the opposite is true:) Sorta counterintuitive, but increasing track at one end of the car will increase the outside tire loading at that end of the car, and reduce it at the other end. Cornering speed would go up, but the car would tend toward sliding the end where the track was increased first. Kart racers can slide their rear wheels inboard or outboard on the axle, and move them inboard to increase grip at the rear (reduced oversteer) and move them outboard to increase grip at the front (reduced understeer). Either way, the effect of increasing track only (no camber or toe changes) on a Z by 1/2" shouldn't have a significant effect on overall balance.
