Madlock Posted March 8, 2011 Report Share Posted March 8, 2011 I'm at the final junction of my wheel /tire crossroads – andI'd appreciate any helpful advice or insight that may be available before committing. I will be replacing the OE F-1 G: 2 tires with ContinentalExtremeContact DWS. My wheel choiceswill consist of either the 19" x 10" Ford Racing SVTPP look-alikes, the 20" OEwheels (widened to 10.5") or Forgestar F14s – whose spoke pattern is about asclose to the SVTPP wheels as exists (it's a 7/14-spoke pattern rather than 8/16)and comes in 19", 20" and 22" diameters in widths up to 12" milled to virtuallyany offset you like. I intend to keep the OE F-1 G: 2's for tracking duringoptimal conditions. I've 4 basic reartire choices from the DWS family. 4 x 275/40-19 (on 19" x 10") Pros: 4-way rotation, more front-end grip, OE diametercompatibility and ride comfort. Cons:More front-end pull, more susceptible to hydroplaning andsmaller rear contact patch. 2 x 285/35-19 and 2 x 245/35-19 (on 19" x 10") Pros: OE rear width, shorter rear diameter/quicker (makes the 3.73behave more like a 3.73), more nimble steering with less front-end pull and lesssusceptible to hydroplaning. Cons: Stance lowered by ¾", visual difference (smaller tires tofill the fender. 2 x 315/35-20 and either 2 x 275/40-19 or 2 x 275/35-20 (on 20"x 10.5" Forgestar F14s or widened OE rear wheels and either 19" x 10" or 20" x 9.5" OE wheels) Pros: Contact, contact and more contact. Completely fills the rear wheel arch without rubbing. Maximum footprint. Visual appeal (particularly on 20" wheelsall-around) Cons: Cost (Up to $1,500 more), taller effective final driveratio, greater front-end pull, more susceptible to hydroplaning and car sitstaller (by ¾"). I'd almost consider a4.10 or 4.30 ring and pinion to offset it. 2 x 295/25-22 and either 2 x 245/30-22 or 2 x 275/35-20 (on 4 x 22" x 10.5" Forgestars) Pros: Improved hookup and visual appeal, but this setup would beall about handling – perhaps even better than OE on the track. Cons: MUCH harsher ride for daily driving, shorter sidewall maynegate rear width increase, requires aftermarket wheels with no OE center cap, mayeven buy a third set of wheels on 18" for comfort driving. That's where I am at the moment. I'd really appreciate anybody's insight andthoughts as to: Whether my presumptions and suspicions are accurate Anything I may have overlooked First-hand experience with all or part of any of theseoptions Suggestions for improvement It's probably important to know I intend to upgrade to theFord Racing Dynamic Damper kit – so I can have a bit of control over ridecomfort beyond sidewall height. Thanks, in advance, to anybody with any helpful advice to share. Link to comment Share on other sites More sharing options...
