For example with Speetech arms you can do a simple redrill of the control arm shaft mounting on the frame and effectivly Gulstrand your car without cutting off the bracket and re welding.

Feel free to call and discuss all options.

Hello Frank,
If I purchase the F6769RAP BB Kit which is the Speed Tech Upper and Lower A Arms with QA1 Coil Over Shocks, Do I still need to perform the Guldstrand Mod? Is the Caster adjustment of +5 degrees not built into the new cross-shafts?

I don't mind having to to perform the mod, just looking for what will give me the best performance at an affordable price.

Will I need to go to "tall" spindles to get a lower stance or will the coil overs adjust to about 2" lower than stock.

So many questions...

You only need to do the G mod if you want to. and only if you do not do the tall spindles.

The arms have 4.5 deg built into them not the shafts so 5 deg is no problem

If you go to the tall spindle there are really only 2 options one the ATS has a 7/8" drop. I would not recomend the 2" drop spindles with a high back space wheel as they tend to cause clearance issues.
generally the qa1 kit will get the car down as low as you need it.
We are also going to begin developing the same style of coil over set up using the Ridetech shocks and a swivel top mount using a true coil over shock.
OR there is the Chicane upper conversion, using either QA1 or Ridetech coil overs. with the combination of upper/lower arms, swaybar.

how many options would you like???
hope that answers the ?'s
sorry to jump in Frank

Thanks Frank... You have answered all my questions.

All I have to do now is save up for the front suspension.
