Has anyone here done a k-member install? I have been considering going with a Griggs front suspension. I was hoping that someone here had done something similar. I wouldn't mind doing the whole front clip while at it.
I'd probably have it done at the Griggs shop since I'm not far away but I'd like to know how others like it. Griggs says that older Stangs have the potential to outhandle new ones with the same suspension.

I think I need to do a little more research on this, but I don't think early model mustangs have k-members. They are in the late model cars, and are basically a cross member with the brakets to hold the control arms on, as well as the motor mounts.

I guess you could some how work this kit into your car, but the modifications would be extremely elaborate, and pricy. You'd be better off with a mustang 2 conversion, or the TCP coil overs..

You are correct. They don't have have them but adding them is one of the only ways to correct the suspension geometry or at least that's what I understand. Also it will rid me of the shock towers.

I have looked into the Mustang II suspension. I understand that it will improve on the old suspension but not give me the type of handling I want.

The suspension upgrade I'm talking about basically ends up looking like a coil over setup. I think what is different is that these guys have taken that same setup and made it specific to early Mustangs. It is expensive but I wonder if the other system can compare. I've heard great things about Griggs. The front works out to about $5K in parts.

I still have a lot of time to decide. Thanks for the input.

Hi,
The Griggs kit is really major surgery and cost around $8000.
I would try the global west or TCP front end setups and save your money...

Do you know anything about the difference in handling between one and the other?

To really analyze every facet, you will have to graph camber curves etc... of each setup.
I don't doubt that the Griggs stuff is good, but at what cost? For a lot less money, the TCP stuff will get you close I bet.
The main advantage to me of the griggs is that setup eliminates a lot of the shock tower.

Maybe I should call TCP and Griggs and see what they have to say. It would be nice if a couple of guys with Mustangs had these different parts and could share with us.

It looks like I could probably remove some of the shock tower with even the TCP set up.

I started another thread asking which system the members here would choose and why.

Jas,

I've never used any of your choices, but my neighbor works for Griggs and says they are fantastic! I'd go to sears Point and talk to them, maybe they'll take you for a demo ride on the track?! Assuming money is no object, of course. Most of our racing members are drag racers including me. We just want light weight and weight transfer.

I had some repairs done on my ride by one of the designers of the tcp coil over system (Kerry over at outback restorations in Loomis, CA) and he told me some pretty interesting stories about those pieces. First off, the racing coil overs are about as good as it gets, not much to get into about that.. The upper control arms are identical to the stock replacements minus the spring perch tabs. Everything tubular.. everything 'perfect'.. now the only question, do you get the same skidpad numbers as the griggs kit.. You might want to give Terry at TCP or Kerry at Outback Restorations a call and get their insight on that. One thing is for sure though, the TCP kit is damn tough, and with their testing, you can almost garentee it to hold together through all the demanding turns you can put it through. I'd go with this kit almost for sure, save the money for the suspension in the rear end. (IRS from a jag?)

Thanks Steve.

Actually I know a lot of guys from the newer Mustang camp can't get enough of the Griggs components. Many of them say that nothing is better.

I have spoken to Griggs before and they seem like really nice people. I only live about 30 min away so getting out there is really no problem. The only think I am concerned about is that I don't really have anything to compare with outside of the modified suspension in my car now.

My point is only that the TCP system might not be as good but the difference so slight that only a pro would ever notice. If this is the case I could save about 50%.

I'm just trying to get some info so I can start to figure out what direction to aim. I need to budget things like this way in advance to squeez them in. I am thinking early next year at this point.

Thanks.

Hmm.. I just found the webpage for that kit your looking at Jas.. looks awesome. If you want peak performance, I'd have to say this would be it, and if price is not an issue..

For everyone else that is interested..

Appreciate the info. I'll give TCP a call. I have thought about that IRS for the rear. It would be great to see an older Stang recording faster laps than newer sports cars(like my Z06) and no outward signs that it has a modded suspension. That's really what I want to do...eventually.

Steve - I'm about 90% that I'll be up at Sears Point Wednesday. If you see a black z06 it might be me.

Jas,

Sears Point will be closed this Wednesday. An unscheduled closure due to construction!?! Bummer, but it should be open again on the following Wednesday (5-2-01) I look forward to meeting you (even if you're driving the Z06) LOL

SteveW

p.s. You can check out a 351w installed with shock towers. I'd sure like to get rid of them!

Well then the Wednesday after it is. The Mrs. says it's a sign that I'm not meant to race. I told her no that it was just a sign that says I suck at it!

Oh and it took the Z06 to get me over to that camp and they still don't compare to the Mustang folks.

Jas,

It's cool, but remember that the latest from GM is 'the competition' for most street driven classic 'stang owners. Nothing gives us more pleasure than beating them! You have one too (stang that is) so you know what I mean. I see from your posts that you want the 'stang to run like (or beat) the Z06. How does it run anyway?

Steve,

I know exactly what you mean. I used to love to rip the newer cars when I drove my Mustang around. I mentioned my mods in an earlier post.

My Mustang runs well. It is without an engine for a couple of weeks before a stroker goes in. It was never a quarter mile car but even in top speed trim it ran high 13s at 107 (3.0 rear). It only ran the quarter twice and I don't want to make excuses but based on the comparison to my Z06 it was an easy high 12s low 13s car. I can't comment on the new combo yet but I'm looking for 100hp more than the last setup. It will be tuned on a dyno a few weeks after it's running.

The Z06 is truely an amazing production car. Most guys I know run 12.5-12.8 stock with the good drivers running 12.3-12.5. The mph is generally between 113-116. It's a tough combo to beat. On the street there are few cars I'll run across that are faster. The mph tells the tale. Most hot rods don't have a chance from a rolling start. I'm guessing my Mustang will be faster from a roll but the lack of space for larger tires will limit the 0-30 time. The handling however will take big $$$ to compete with. This is why I have been asking about all the suspension stuff.

Nice Mustang btw.
