Whats the difference between these and the 500/510 series?
First, I will answer the common Fortune 550 question vs the competitor question.
- Extended Warranty
(2 YEARS Internal / 5 Years External) - Much longer than everyone else out in the market.
- Revised and Tested Valving
We have revised the spring rates and matched the valving to these spring rates for a nice optimum between street daily driver and the occasional track race.
- Shock Dyno'd before leaving the factory
Every shock is hand assembled and shock dyno'd before it leaves the factory in VA. This is a nice way to confirm every shock is to the exact specification and isn't built in Taiwan, put on a container vessel for months at a time and then lands at your front door.
- AMSOIL Authentic Oil Utilized
AMSOIL USA oil is used in every shock to ensure that every shock operates the same exact way in hot and cold. Plus this oil is from one of the best oil manufacture's in the country.
- Assembled by hand in the USA! Right in Virginia!
Nothing better than one guy who takes the time to build and certify each and every shock at 45min to 60min each shock! It's a lengthy process but ensures quality craftsmanship in the good ol' VA, USA.
- Shocks are matched for springs on an in-house SHOCK DYNO
This gives Fortune Auto the facts they need to know that each individual coilover is performing the way it should. Nothing is built and then just thrown in the box. It's all MATCHED and VERIFIED in house.
- All shocks are dyno matched before they leave the factory
Going back to the shock dyno, the shock can not be more than a 1% difference from the other. If not, they take it all back apart and start over!
- Spring rates that actually match the weight of the vehicle and not random rates
We have gone though rigorous testing of different spring rates and valving types to make certain this is going to work with the mean average weight of your chassis with respect to it's driving style. Countless hours were spent to correctly identify the correct spring rate for you.
- Shocks actually perform as they should over the years, they dont diverge as they get older
What can happen over time with other coilovers is that they can change over time. Valving wears down. Seals wear down. Pistons wear down. Oil viscosity doesn't stay the same and wears out. Fortune Auto coilovers perform the same with YEARS to come. We have seen roughed up rallycross coilovers used to their fullest potential for years, but them back on the shock dyno and they are STILL perform next to good as new.
- Full rebuild-able and serviceable in the good ol' USA
Yes! No need to send them back to Taiwan or outside the country. Send them back to Virginia and the same patience taken to build them from brand new, the used shocks will be catered to in the same way. Fortune Auto doesn't just send you a replacement shock with a random wide range of valving and hope for the best. They re-match and re-calibrate the shock to the spring, good as new!
Last but not least, the 510 series is STRICTLY a track oriented coilover. It's valving is very aggressive. To break it down in a super simplified way.
FA 500 = Street Car with occasional auto-x/spirited driving
FA 510 = Dedicated Track Car. Very aggressive valving.
FA 550 = A dedicated line of coilovers for tried and true application specific racing. These are dedicated Drag Coilover for MK3 Supra. The same way FA 550's are drag coilovers for the MKIV Supra crowd.
