Hey guys. I went for an autocross event yesterday, and I had a kickass time. I ran the 1.5 mile course at a 142.xxx second personal best time, down from a 198.xxx opening run. I found some things about my car I want to correct though. When I launched, it felt like I got some wheel hop, and I know control arms will take care of that. Which control arms are good for road courses and autocross? I also had an issue with my oil temps getting up to 205-210* on my gauge. I was told that 220 was the danger zone for dino oil. Since I'm seeing 4-5000 RPM at all times, and you can't really shift, I have no option but to heat it up. I want to get an oil cooler, to help keep those temps down and preserve my oil. I know Summit carries a few, but they're pricey. A friend has a cooler adapter block on his 2.3L motor, and he asked if I was interested in it. He has a spare one on an extra block. Will this adapter fit my block so I can piece together my own oil cooler kit? Also, my brakes were kinda iffy, but I think that's because I did the SN95 conversion all around and never upgraded my master cylinder. I'm going to get a 94 GT MC for now, but by next year I plan on Cobra brakes up front, and a bigger MC and booster to support them. The car felt like it hooked good, and my tires took a beating, but that's expected. Overall I had a blast, but just wanted to get some input on those three things, the control arms, oil cooler, and brakes. Thanks Guys!
 
Everybody has there own favorites when it comes to control arms. I'd say that any aftermarket arm is going to be better than stock. Bushing choice is going to be a matter of personal preference/driving style. I don't see subframe connectors on your list. SFCs and control arms will give your car a whole new feel. Let you stay on it longer in to the corners and get on it sooner coming out. I also don't see a driveshaft loop. I like a loop on any modified vehichle that gets called upon to perform beyond the normal wear & tear driving. JMO.

I'm a little confused about why you're opting for a 6spd. If you don't shift much on the track, I'd think a TKO II/Tremec 500/600 with the 5th gear delete would be a better performance enhancement. Less weight and less rotating weight in your driveline. Tremec claims they've tested the 600 upwards of 1300hp.

How does your water temp relate to your oil temp? You may consider an aftermarket aluminum radiator or a bigger fan. Or possibly a manual/adjustable controller on your existing fan would help bring your temps down. I don't know if the adaptor you're considering will work or not. Zirgo has some nice fans if you're interested. Thin profile & lightweight. I've got twin 12s for my 408. Only 2-1/4" thick. Best deals I've found on these are on eBay. Maybe an aftermarket radiator for an automatic transmission would help you out on both temp guages. Just route your motor oil through the AT ports on the radiator. May be less weight than a separate cooler.

Well these are just my thought on your post. I hope you find something useful in them.

As for the brakes...I've never fooled around with conversion setups or aftermarkets, so I have nothing useful to offer.

Good luck & congrats on the SC.


EDTI: Try asking over at EastCoastStang. I know there's a few guys over there that autocross regularly. They could probably offer some more useful info.
 
There is no need to go any bigger than a '94/95 MC even with Cobra brakes.

Unless your rear calipers are huge, like mine, which are 54mm. Very close to your stock FRONT 87-93 5.0 calipers :D. I have an SVO MC because of this.

The SVO uses 73mm calipers up front, and 54mm in the back. Should I have a SN95 MC, I fear that my pedal will be very low, and soft.

Go with the '94/95 MC.

As for control arms, I love my MM pieces. They are made for road racing, and have the spearical bearings on the axle, with greaseable urethene bushings in the front.

The oil cooler is totally optional. I should probably have one, since i have very high oil pressure (remember, pressure = heat) AND an oil fed supercharger. I'm in no rush to get one though.
 
I have subframes, I have a MKVIII electric fan with a DCC controller, and I plan on getting a junkyard piece tranny cooler for a power steering cooler. My water temps stay at 190* at all times, and as soon as I roll off the course, it's 196 at best. Oil temps go alot higher, but I found a sweet variable kit that FRPP sells. I plan on getting that. I like the control arms Chris has, the MM ones with spherical bushings, and I know that'll help with open tracking and autocrossing. I need to get some race seats, because I was getting tossed all around in the stock GT seats. I want 4 pt harnesses too. Here's my whole setup, tell me where I should go from there for this type of racing:

I know some of that stuff has nothing to do with racing, but I had that list on my CarDomain page and I am being lazy.
 
I bought the MM non adjustables with the spherical/urethane bushings. They are nice pieces, and from all my research, they are the BEST (comparable to Global West, same arm just the bushings are reversed) all around control arm for road racing and drag racing. The spherical bushing is the biggy, especially with road racing. Side to side movement with hard urethane bushings will tear up your torque boxes, but with the spherical bushing, you prevent that because it allows for some movement side to side when cornering.
 
Comparable but i doubt identical. I read that someone had compared the two, brand new out of the box side by side and by the naked eye, they are very close but the MM's looked thicker/felt heavier.

I love mine and the welds on them are MINT. Can't wait to bolt em on.
