Default Alternative to GFL A-Arm and BSK?

Has anyone used this product before?

I know you guys probably think its a tuner toy, but all I want is 1-2 more degrees of negative camber, not the +6 I get from the A-arms.

I'll only drive 4-5 times a year on the track. Will they work as advertised?

After a quick search I found

https://www.s2ki.com/forums/index.ph...=257298&hl=spc

and

https://www.s2ki.com/forums/index.ph...=246023&hl=spc

Both posts did not give much detail, except some worries as to changing the location of the suspension points possibly having some negative effects.

rlaifatt--what did you end up doing?

Richard has those camber kits on his white car and aftermarket a-arms on his grey car. His white car is damn fast, so it seems to work fine. He's never had them come loose or anything.

As to alternatives to the BSK, if you have a good fabricator, they could probably do it for you, but if you're not sure how good your fabricator is, then you would probably want to stick with the GFL BSK.

Also, just FYI - note that this is the "Racing and Competition by The Go Fast Lab" Forum... so...

BTW, as to changing the angle on the upper a-arm with the camber kit...

I thought about that issue a bit and realized it shouldn't change the geometry at all. The frame mount locations don't move and the upright mount location doesn't move. So whether the a-arm takes a straight path between those three points (as it does stock) or a curved path (as it does with the camber kit) should not change the geometry of how the suspension reacts through its motion at all. If that doesn't sound right, draw it out on paper for yourself. The shape of the a-arm changes, but the mount locations don't. So even if you shape the arm like Austin Powers' medallion, it will not change the geometry, just the camber/caster and structrual indegrity of the arm.

I know it is not a repacement for the BSK...but it can adjust the rear camber just like the front, which is the only reason I would want the BSK (read, camber)

I think you're confused. The rear can get enough camber usually even in stock form. It's the front that needs more camber and it's the FRONT where you use that camber kit. The bsk is not a camber piece at all. The bsk relocates the attachment point for the rear toe rod so that it more closely mirrors the attachment point at the chassis. By having less disparity between the two mounting locations, the toe change during suspension compression and decompression is greatly decreased and the car behaves in a more predictable manner.

That's not entirely accurate. While the primary purpose of the bsk is to correct the toe change problem, an added bonus is the greater adjustability in camber range. Because you can vary the length of the tie rod, you can dial in significantly more camber than stock will allow. Stock suspension limits you to just a tad over -2 deg in back. The bsk allows much more.

To robinson... because of the correction of the toe problem, the bsk is defintely worth spending the extra $$ over this ebay camber kit. The bsk is a very high quality unit, and you'll be really happy with your purchase the next time you're in a slightly bumpy high speed sweeper.

Here's my mad paint skills.



The ball joint in the first image moves the upper a-arm up making it not in the same plane in relationship to the lower one as the stock suspension. Whereas our arm doesn't move the upper arm up, it just moves the upright in.

Moving the angle of the 2 arms in relation to each other can have all sorts of ramifications due to what happens as the upright moves thru its range of motion. That being said yes there are people who have used the ball joints and they do give more static camber. But I'd need to put them on a bumpsteer gauge to measure exactly what they're doing. No one that has run these ball joints (at least as far as I know) has actually measured what changes thru the full motion of range. Whereas we have spent almost 2 years developing ours.

Same goes for the BSK, and frankly John I'm a bit annoyed that you would encourage people to knock off our products. Sure any fab shop can copy someone's design maybe for less (if they get it right on the 1st or 2nd try). Our BSK consists of a number of custom designed (and CNC'd) parts that we developed thru many rounds of testing. Again the first BSK was on my car almost 2 years ago and it saw many revisions before we started selling it.

So the bottom line is with the GFL products you get something that has been engineered by someone who knows suspension design and has been significantly tested by myself and davepk.


Thats my 2 bits.

Don't forget me
I had the first 'street' version on a 'street' car

I recently upgraded to the full-race kit, which are very easy to adjust the toe with.

You can do the same with the Jsracing Ball Joint. The only diffrence is you change the lower joint and not the upper. Price is ~~350.
