Which is better for autocross? Ill be running coilovers, and this is for my 90 GTU.

I'm running the AGX's and am happy with theem

Your opinion doesn't count..cuz you're an eggplant..

Anyone with Konis?

I dont know much about the Koni's but in most cases you get what you paid for. Koni is a very reputable company. I have the KYB - AGX and love them.

i've heard that koni shocks blow seals fairly often, compared to other shocks at least. however, i think that the konis come with a lifetime warantee. what are the prices on each set?

I dont remember prices offhand, but I wont be paying anywhere near list for either brand, anyways.

I am a Tokico fan myself, but my opinion doesn't count because I have their base line "HP" struts which aren't adjustable, but a lot firmer than stock. There is a guy on the club with a full set of RB springs and Tokico Illuminas for sale for $450 . . . mmmmm . . . but I am not ready to ditch my Eibach springs until I know that they are holding me back on the course. Driver skill appears to be the biggest factor to auto-x times. Good driver skill can shave 10 seconds off a run, but struts and springs might give you a couple seconds at most. Of course, they won't do much without full camber adjustability and sticky tires.

Because of my engine mods, Im not going to be in anything even resembling a stock class. I already have coilovers, but Im looking to get new shocks and some stiffer springs in the near future.



Im kinda debating going with a full coilover setup, like the JIC. With what it costs to get camber plates, shocks and springs, it wont cost a lot more to go with a matched set.

I'm with you on being in SM2 or some other modified class. My relocated battery puts me in mod automatically. Without that I would be in prepared due to engine porting, but really, it doesn't matter to me. Top time is always the goal! I have to beat my friend with the ASP FD who usually owns the events around here.

i love my agx's too https://www.nopistons.com/forums/pub...#>/biggrin.png

We've had both: AGX's about a year and a half ago and the Koni Sports (Yellows) now.



I think the AGX's are a pretty decent unit and wouldn't be afraid to buy them again; a pretty good bang for the buck. However, I think the Konis to be a little better with regards to performance at the limit, rebuildability (sp?), adjustability and reputation.



Either way, you're getting a good shock. You might consider your application and future goals.

Yeah, but the AGX's are red. https://www.nopistons.com/forums/pub...#>/biggrin.png

Its not like either of them will match anything else on my car anyways...

So the AGX's aren't adjustable like the yellows?

Both the konis and KYB AGX's are adjustable.

The AGS are adjustable and on the rears the adjuster is on the side of the shock so you can adjust without removing pieces....

But I dont have pieces in the back, thanks to my rear strut bar. I think Im going with the Konis.

konis are a good choice

it really depends on the spring rate, but either shock is a good choice for normal fc spring rates

You might want to double check the rules but I don't think a relocated battery puts you out of prepared. You should still be able to run there.

I have FC Rx7 Koni yellows all round in my Cosmo (don't ask!). According to my suspension contact as they come delivered here they will handle up to a 400 spring front and 250 rear. Yellows are rebound adjustable only via a tang in the top of the shaft. You get a plastic key with the shock. If you have camber plate style front strut tops the key needs to be ground to fit inside the nut. Koni Red has bump and rebound adjustment, adding a bump knob on the shaft to the tang on top but are almost exactly 100% more $ here!

I was dubious about hydraulic only but have been converted. They seem smoother & better controlled, and are fully rebuildable. There is a custom valving service available too which I havn't tried yet. I know some racers here using Konis have had a valve set built to suit the local track with very pleasing results I would be sure they would offer the service in the States too..

has anyone tried the koni that are offered by ground control that are apparently revalved for racing applications?
