Default pfadt question (pics inside)

Hello,

I just bought a set of used pfadt coilovers, and would like to know what spring rates they are running, I know the rears are 600 pounds eibach springs i can see the codes clearly, but the fronts carry A8.2x229 code on the spring.
I searched the net a coudlent find anything for A8.2x229 springs, could it be 229lb front springs ?


another question are these the Drag Package or the Street Singles


here are some pictures:

Hey there! So like I mentioned yesterday via email those are the street version of the FeatherLight Singles. You're looking at a 460 Front lb/in spring, and a 600lb/in spring.

Let me know if you have any other questions!

The damper bodies themselves are definitely built in house now. There was an early batch that was equipped with Eibach springs, and given that this is a used set it's probably one of the little earlier batches. All custom drag and high rate track spring packages usually ship with Eibach springs.

Even though the spring says Eibach, the damper body it's self where all the magic really happens is a Pfadt unit.

Well you've got a couple options. Both the Johnny O'Connell and the Heavy Duty - Light Rate sway bars are going to have rates that will work really well for street cars, it really comes down to how much adjustability you need and what your budget is.

Our Johnny O'Connell bars are our bent bar option, budget conscious, and work great for folks using their Corvette on the street and track. They are a fixed front bar, with a 3 point adjustable rear to help you dial in the car for your particular driving style or tire compound.

The other option are our Heavy Duty - Light Rate sway bars. They feature both an adjustable front and rear bar, are built around our 3 piece bar construction technique, and have rates suited for street or track use with street tires. The Light Rates are overall lighter than the Johnny O'Connells and ultimately the adjustable front and rear make them well suited for customers looking to get the most out of their bar packages.

How about the HR swaybar and setting it to the soft setting ??

Will the HR SB work good with my singles ???

Thanks

It depends on what you're doing with the car. If you're tracking the car aggressively with race tires the Heavy rates are a great choice. If you're driving the car on the street and never see the track they're going to be overkill. There is a really broad range of adjustment with the Heavy Rates, and you CAN drive on the street with them... but ultimately the Light Rates or Johnny O'Connell bars are a better choice for pure street cars.

I'm kinda torn between the Johnny O'Connell bars & the Light Rates. 2002 Vert with F45 package. Michelin Pilot Super Sports- 305x19's in the rear & 275x18's in the front. Aggressive street & canyon carving with two autocross days a year. Maybe two track trips a year, but only at moderate speeds - no excursions off track.

The most important objective is enhancing the aggressive street and canyon performance where 90% of my driving happens. The other stuff is just for fun.

Only 23k miles so probably won't be switching to your Feather Light SA's or the Bilstein Sport Shocks for a couple more years.

Thanks.

If you're not concerned about the slightly heavier weight and the fixed front bar, I think the Johnny O'Connell bars would be a really good fit for you. What they give up in adjustability they make up for in price point. For cars whose life is spent almost exclusively on the street we recommend the Johnny O'Connell bars.

I am also looking at the JOC setup with the sway bars and shocks. Living in Seattle WA with the hills and uneven drive ways, railroad crossing, I believe the JOC is the right setup and plus great price. But would I be able to replace the shocks later with the light rate coilovers and not upset the balance of using JOC sway bars? I plan not to do any track days, but like doing canyon runs and have a favorite winding road I like to drive on during the weekends.

You will bump up to higher spring rates when you move to coilovers, but in our experience the JOC sway bars are still an excellent fit for the FeatherLight Coilovers. You can definitely pick up the JOC package now and upgrade to coilovers at a later date for even more adjustability and control over your suspension.
