Don't get me wrong, I ordered the endlinks and ITR cnc machined inserts and i got them as soon as they had them in stock. But when one of the bolts unthreaded and i lost the cnc inserts on one side, i emailed and called about getting a single-side replacement. Owner said "yeah, i can write you up a special order, just send me an email right now of what parts you need and make a note that we talked on the phone" Well, I did so, and got nothing in return.

maybe so but tell me how to contact them if they wont return emails, and dont answer the phone, and david-r really is the only response I can get but I think he basically just sells and does not deal in customer service.

Damn that sucks for both of you guys. When I ordered my LCA's I only spoke to them through email, and I got responses for each one within a few hours. Maybe send them an email with a link to this thread in it? That might bring it to their attention.

I don't care anymore. I just put the OE rubber bushings in and went to ACE to get new hardware. Holds up fine now. F7 isn't worth the hassle anymore.

I give customer service to my customers wherever I can. I don't show you as a customer of mine, what do you base your claim on?

what? well I have purchased f7 lca's from you and f7 endlinks from another HT member, thats what I base my claim on. Im just not satisfied with the endlinks and I just want some answers or a refund. I do appreciate you because like I said your the only F7 person I can get any sort of information out of.

My email is r.moon@mchsi.com check your base for that and you will see my purchase of the f7 lca's

Ahh, there you are, purchased from my web store.

Since we're on the topic of unsprung weight reduction, has F7 or anyone else ever thought about making an aluminum knuckle to replace the heavy cast-iron ones we currently use?

And how much of an effect does reducing the weight of these suspension arms really have anyway? Is it actually noticeable?

I think it would be noticeable, but you'll have 10 people saying "just take a crap before you race". &lt;/end sarcism&gt;

I think what you have to think about in designing/producing a product like that is the design/engineering/research costs vs how many will sell at a cost where you'd recoup. That would be a very large chunk of aluminum, and when you start talking about adding the conical wedge mounts for the upper ball joint and steering knuckle, things get complicated in a hurry. The other thing you have to consider is would they be "legal", because surely if you are going through to redesign the knuckle, you'd change up things like tie rod location.

Mmm, bumpsteer correction. I'll take me some of that.

And a shorter total knuckle height (increase UCA to chassis clearance). And a relocated hub (lower ride height height). And some extra static camber (why not?). And an increased negative scrub radius (maybe). And and and...

Come on, we've conversed through email several times and we told you that you had installed the linkages wrongly (bolt, through arm, small nut, through linkage, large nut) and that our linkages are designed for track cars and require regular maintenence, and are supposed to be lightly greased.

We back up all our products with a warranty, unfortunately it does not cover user error. Besides, we use large DIN-sized heim joints for our linkages -- the male spherical joint in your pic is not a DIN sized joint (i.e. the side with the male thread). Who did you purchase the linkages from?

Function7, if you guys put out lightweight front lower control arms that add caster, I'd snag me a set literally the instant I had the money. I've been interested in the front LCAs for a while (Omni Power makes em), but have been weary of spending all that money solely for a tiny (effectively) difference...with the added bonus of more positive caster, it definitely sweetens the deal enough for me to definitely want one.

I'll check back from time to time to see your progress on this.

Keep it up guys!

Yup, back on topic. Any estimated time of completion for these? Give us the scoop on some other products you're working on.

Watch out on the caster, it screws up you bump steer curve and a little caster vs. alot of bump steer is not a good compromise.

True, caster will introduce some extra bump steer and torque steer in our cars and increase steering effort slightly, but it also helps with negative camber gain on the outside wheel when turning (without more static negative camber), which helps in a straight line (less static negative camber = better off-the-line traction and better very high speed stability) AND in the corners (negative camber gain on the outside wheel when turning, so outside tires have more contact with the ground in hard cornering).

The extra little bit of added bump steer and torque steer is more than an acceptable compromise for me in the face of the above bonuses, especially because I'm not running any serious power adders.

"Soon".... can't say much since it's our company policy not to divulge any information until we are good and ready to release the product. Rest assured that your concerns about caster/camber/etc will be addressed.

Sorry for the slow replies - we are insanely busy right now and I haven't had the time to come check HT.

no, i have never received any emails back from you guys, only david r's crap IM's just like you just fed me back. like I said they "worked" like a charm for 6 months and got louder and louder when they wore out. Yes I know you hate it but these are your china function7 endlinks, im sorry they suck, i just know that I wont be purchasing any more of your products and I am left with a sour taste in my mouth about your service in dealing with such a small problem, but I guess its the little things that add up. You also just cant hide the fact that these rusted to **** in 6 months and we have no snow here. I couldnt imagine what they would have looked like in a year.

Look, I don't know what has been exchanged between yourself, Function7, and DavidR, but this is not the place to continue it. If you feel the need to complain about a product, please start your own topic or use the private message function.

Now, back to discussion about front lower control arms . . .

They're also a wear item, if you don't properly maintain them like you should have, and DIDN'T then you wouldn't have had any problems... you're the one who fails, not the end links. Take your BS crying and finger pointing else where.

it doesn't need to snow for surface rust to form.....its in the air. according to your profile you live "on the farrr east coast", there is a huge ocean directly east of you that contains salt and water. occasionally storms form and wind direction comes from the east to west...meaning any water vapor will travel inland. i have some surface rust on a car that is garage kept, it never goes outside.....but because i live 10 mins from the beach, the air has "salty" content to it. its natural and ever occurring, you can't help it......or can you? the army used to coat all metal surfaces with cosmoline(sp?), it's grease, so that metal surfaces would not rust. hell even a light spray of WD40 would be enough to slow down the rust formation. why are cars painted in the first place? to PROTECT the metal from the elements. not for fashion, that came later...... ford model T, any color you want...as long as its black. paint is like clothes....

again, where do you live? are you within 100 miles of the atlantic ocean? if so....that's why untreated (clear coat, paint) metal rusts. basic maintenance will keep it new looking and perform like it should.....spray it with WD40, the rust will disappear and will inhibit the rust from coming back.
