I was hoping anyone with RB springs would comment on the ride quality. Also what tires are you running? What shocks do you have?
All I can find is how much they lower the car but nothing from anyone commenting on the over all ride impression/quality.

I have them on my FD, with Tokico 5-way adjustable shocks. They lowered the car 3/4" in front and 1-1/2" in rear. The car looks more level than stock. The ride is very good, but can change dramatically with the shock setting. Note the spring rates are 260 ft/lbs in front and 212 ft/lbs in rear and are linear opposed to progressive rates.

I've had the Racing Beats with both the stock R1 shocks and with the 5-way Tokico Illuminas. On the public roads the R1/RBs were punishingly hard. The RBs with the Tokicos on setting 3 was much better, but you'd have to switch to setting 4 or 5 for track work. The RBs were fantastic on track. This might have something to do with the linear spring rates. The RBs were very predictable upon turn-in.

Because I drive my car daily, I switched to a progressive spring rate OE style spring. My current springs are H&Rs over the stock R1 shocks. The ride quality is outstanding compared with the RB spring/Tokico Setting 3 setup. On track they aren't as predictable as the RBs/R1s or Tokico setting 4s were, but I became accustomed to the split second delay in wheel/tire loading during during the turn-ins with the H&Rs/R1s.

My road tires have always been the stock 225/50-16 sized tires. The brands differed between Bridgestone S-07 Expedias, RE71s, Pirelli P-Zero Asimmetricos, Kumho Ecsta 711s. The best road ride quality came with the H&Rs/R1s with the Bridgestone Expedia S-07 tires. The Pirelli P-Zeros were a close second.

I have RB springs with stock R1 shocks for 3 years now, with stock rims and 245/45/16 tires. Ride quality is diminished from the stock springs, mostly over rippled or rough pavement. This combo is really too harsh for daily driving unless your roads are very, very good.

On the road course the RB springs are a major improvement over stock springs. No abrupt nose dives under braking, and turn-in is "right now." The car reacts very precisely to small steering inputs unless you've (I've) been really stupid.

Aesthetically, I'd like to see the rear of the car sit maybe 3/4" lower than the RB springs allow. The front fenderwell gap is about 1 1/4" and rear is about 2".

I had the RB Tokico, setting 4 at Mid Ohio '99. I spun twice... never got signed off the whole weekend. Day 1, spun in the morning coming out of the Carousel; Day 2 spun coming out of Thunder Valley, with Norm Falilck just about to T-bone me...gave him a thrill, at least

The RBs springs were so right now at turn-in, it was too much. The RBs were outstanding autocross springs, especially when coupled with the Eibach Comp sway bars. Unbeatable combo, IMHO.

So will I see the Cincy crew at my March 23 Putnam Park event? It would be cool to have the FD Rx7s make some of my Porsche guys scratch their heads over the laptimes hee, hee :p

I have the racing beat springs with the bilstein shocks and my car rides stiff as hell!!!

thanks for all the great information,
I thought from what I had read, that the RBs would be a nice spring to be slightly better then stock.
The springs currently on the car are a no namer lowering spring they slam the car in the weeds and that's about it. They are on koni shocks so that is a good start.
What Im looking for, is a good street spring that will improve handling and only slightly lower the car. I drive 25 miles to work with the first 10 being real back road driving. (ie no lines on the road). So Im looking for something mildly to non punishing. I also live close to skyline drive and shoot up there whenever I can.
now that ill stay away from the RB springs, what would the best street spring be with my koni shocks? Im not looking to lower the car more then an inch or so.
Also for anyone with koni shocks, the perch is adjustable. where is the stock setting upper lower or middle?
thanks

So these springs are good for autocross? I ask, because I'm looking at springs and coilovers for autox, street, and road racing application. I'm not too big on spending $1,500 or more on coilovers when I think that they will be overkill.
I love the fact that the springs are linear, and that it brings the (jacked up) look away from the rear. Since it lowers the car more in the rear, doesn't that mess up the weight distrubution? I mean its almost 50/50 stock right, and everyone is always talking about corner weighing the car to make 25% on each corner, is this a problem?
The price is right on the springs, and I have a R1 so they will go with the low mile stock shocks. I'm not worried about the harshness of the ride, as I feel I can go stiffer than what I have now. (How can people complain of the ride of a stock R1?)
Thanx Guys

Oh yes, these are great autocross, slalom racing springs. Be sure to get a set of Eibach Comp sway bars to complement the springs. You'll be untouchable, especially if you're running Hoosier A3S03s or some sticky rubber!

IMO, the RBs even the car's ride height very nicely. With no one in the car and full tank of gas, the rear end is slightly higher. With a driver and full tank of gas, the ride height is dead even, fr/rr.

Corner weighing is overkill for autocross racing IMHO. If you've got the gift for tossing the car through the cones faster than anyone else, that's 90% of the battle right there!!!

Good luck!

My recommendation would be either Eibach or H&R springs. Both are progressive rate, and will work with your Koni shocks. I have direct experience with the H&Rs, and I can say that with stock R1 shocks, the H&Rs give a better ride quality than the stock coil springs with R1 shocks did! H&Rs drop the car ~1 inch all around. The Eibachs drop ~0.75 inches all around.

I don't have any experience with Pettit's or PFS' springs. Both are also progressive rate. I've read that Pettit's springs slam the car pretty aggressively (>1 inch), while the PFS springs are much more conservative drop (~0.75 inch).

I don't recommend the RBs unless you're a competitve driver, or do drivers education weekends every weekend!

Good luck!

Thanks for the useful information.
Anyone else care to mention their impression of the Eibach or H&R springs? I would really be interested in them with a koni setup.

The Cincy RX7 guys are always ready for Putnam or Mid-Ohio. We hope to bring a min of 10 cars to each event this year including a few ITS FC's. BTW, has Nelson Ledges been repaved?

I had RB lower springs with Tokico 5 way adj, set on 3 and the ride was too hard. About 1/2 yr later, I changed RB springs to Eibach lower springs and the ride is just right. So now I am selling them. Email me if you're interested. Tony

I have the Tokico adjustables on my car with the stock springs, and on a setting of 1, it rides just fine on the street. I was thinking about getting the RB springs as well, but I was just worried about possible rubbing problems with my 245/45 ecstas on the stock rims. I plan on autocrossing the 93 very soon...

Speaking of...what are the spring rates of the stock springs vs. aftermarket?
