Its difficult to explain but i hope that makes it a bit easier to understand.

@86drift so the front crossmember is solid mounted to the chassis? How is it attached?

OHHHHHHHHHHHHHH..........that's what 86Drift was getting at............ thanks both of you ..... learned something new today.....

I haven't been under the car to confirm but from the walkaround on InsideLine: "Meanwhile, efforts to keep weight down and the front end of the car super low have resulted in a forward-facing lower control arm (yellow) and a simple crossmember (green) instead of a full perimeter subframe."

You can see where the crossmember is bolted to the chassis right next to where the lower control arm bolts to the crossmember.

thanks for those pics, very interesting. The control arm has two ball joints it seems, ive never owned a car with that sort of suspension set up but I do like the uncomplicated arrangment.

Are all these products great for street and back road carving, or is it overkill? I've always loved a great handling car, but don't want to overdo it for street use.

It's definitely not overkill. I'd describe the changes to my car as making it more responsive to steering input and having less understeer. Ride quality is still good, just slightly firmer than stock.

My car is yet to see a track, but I'm very much enjoying street driving and the occasional mountain road.

I have an update on specs for the Whiteline swaybars.

The below rates are % stiffness over the OEM bars.

Rear 16mm (3 way adjustable)
Soft Setting - 40.48%
Medium Setting - 88.78%
Hard Setting - 176.58%

Rear 18mm (3 way adjustable)
Soft Setting - 114.63%
Medium Setting - 178.04%
Hard Setting - 263.90%

Front 20mm (2 way adjustable)
Soft Setting - 118.5%
Hard Setting – 174%

Front 22mm (2 way adjustable)
Soft Setting - 218%
Hard Setting - 301.5%

wow those 18 and 22mm sway bars really ramp it up dont they. probably overkill for a street car that will occasionally see the track?

I think they're be to big for a regular street car. Whiteline's recommendation is that they should be used if your running semi slick or full slick tyres.

I'm running 20mm front on soft and 16mm rear on medium and it's fantastic on the street. Once I get some semi-slicks and start racing I'll probably bump them up to the hard setting.

Now I'm a vendor I've been able to bring this thread back from the dead.

Now for some belated updates:

My first race with the products intalled.

What a great weekend. If you get a chance to do a track day grab it with both hands. These cars make you feel like a driving god.

Now for how the weekend went. I tested OEM vs Whiteline swaybars.

On Saturday I did 6 laps on the OEM bars and set a best time of 35.95. I then went out with the Whiteline rear bar installed (on medium) and did a 35.62 within 2 laps. A good improvement. Understeer was greatly reduced and oversteer managed with the right foot. This would be a good drift setup and it wanted to drive sideways around the whole track
On Sunday I did 4 laps with Whiteline front and rear bars (set on medium) and did a 35.33. Once again a good improvement. It was more balanced then with just the Whiteline rear bar. I then set both bars to hard and set a best time of 35.27. Setting the bars to hard made no noticeable difference in lap times. However it was more easily unsettled due to bumps.

As expected the thing holding the car back is the tyres. People in the know say a good set of semi-slicks are worth about 2 sec a lap. Since I was 1.8 sec behind the rx7 race car which won my class, I’m very happy with how quick it was.

Now for one of my favorite mods. Whiteline have released a gearbox mount insert. Or Positive Shift Kit as they call it.

I have to say I was skeptical that it would improve an already excellent shift, but I've had it on my car the last couple of days and it's excellent. Since the gates stay in the same place irrespective of if you're on or off the gas it's easier to slot home the gears.

Huge difference! Looks better than the cusco one I have.

[FT-86 SpeedFactory]

We have the Whiteline positive shift kit on our car as well and love it. Headed to the track this weekend for a time attack and will have video reviews from the track up on Monday.

Whiteline always has had great products and pretty much the only stuff we run on our cars fro sways and bushings.

I haven't installed mine, increase vibration much?

Thx

Me either but I meant in an engineering sense, cusco is solid billet and doesn't provide lateral support like this one seems to.
