Not that familiar with FHI500, but some of turn-in sharpness might be enhanced with tires of stiffer sidewalls. Eg. something from UHP tires, like Michelin PSS & PS4S/Yokos AD08R/GY Eagle F1 supersport/Conti sportcontact 6/Vredestein Ultrac Vorti/Falken Azens FK510/GT Radial Champiro SX2 and so on ..
Of course also keep an eye on tire pressures not too low. Possibly i'd also install steering rack lockdown and maybe rear subframe inserts. Also if it's due alignment .. what alignment camber/toe wise you have now? |

Check toe or newfound steering rack bushing deflection with the heavier/grippier setup.
I've got a set of bushings I've been slacking on installing for a long time, hoping they'll go in soon... |

No point in getting an alignment if you are needing to do it again later after springs/coils. If you do get the lockdowns, check on Ebay as there is a copied version of the Perrin ones for a fraction of the price. I've done everything above including the same Indy 500s but GTF1 17x8 wheels and wouldn't have changed a thing now. |

Thanks for the replies. Yeah I've been debating just springing for springs already but I'm pretty much out of money for car mods this month and I'd like to get the alignment done before the event anyway. I was thinking rce yellows instead of the trd's for the extra ground clearance and if I remember right softer spring rates (still my daily so I'd like to not die from train tracks). Sounds like I'll have to look into steering rack bushings as well. Also these indy 500s are proving to be a deal considering the grip/comfort/tread life you get for the price. 375 for all 4 after a rebate. Probably not ideal for any track junkies but perfect for the occasional autocrosser that can't afford to blow all their money on the hobby.

Having negative camber will counteract this and actually improves steering feel (since your car has a better contact patch under loading). (Too much) negative camber also has some side effects. Obviously, the outer edge of the tire will not be doing much when you're traveling in a straight line and result in uneven tire wear. Camber also cause the car to steer into natural divots and banking of the road due to increased grip bias (the tire that is leaning will pull more).

For these cars? Click.
front: 0 camber, 0 toe rear: -1deg12' camber, slight +0deg10' toe-in. With understeer-ish bias and monstrous +/- "passing" ranges (eg. rear toe from toe in to toe out), at extremes of which car might be PITA to drive and not even track straight or have other handling issues (eg. nervous oversteery rear, if to toe-out). Even if buying it new, even if deciding to stock alignment, worth checking and evening it out if needed, at least once. |

This is my current setup: OZ Alleggerita HLT 18" J8 ET48 + Federal RsR 225/40 + SPC camber bolts (-1.2 front camber), the rest is stock. I also have header/catback/stage2+ and good brake pads and fluids (NED's oil cooler is also on it's way). I'm using the car as DD but also for more than 10 trackdays per season and few mountain runs.
This is my problem: after switching from MPSS to Federal I gained about 1 second on a 2 minutes track but the grip loss is way less progressive/predictable and the front end is more prone to understeer. Fun factor is down a lot. In the long run I'm planning for coilovers but for now I'm looking for a "quick fix" for this (other than going back to MPSS). Based on what I've read on this topic I'm thinking some RCE yellows could be the fix I'm looking for (along with powerflex bushes for camber adjustment that should add an extra -1 degree front camber for some -2.2 in total). What do you guys think? Note: weight (vs stock wheels) with MPSS is about -4lbs per corner and about +1lbs with Federal. |
