Riaction Coilovers any good?

Hi All, I am in the market for some coilovers strictly for street and the rare canyon carving and of course spirited driving. I have an 02 996 C4S. I really don't think I need to shell out $2500+ for a decent set of coilovers just for street driving. I had been leaning towards BC Racing , but recently I was introduced to Riaction which are a couple/few hundred dollars less, are local to me (Cali), and seem to be more readily available. Anyone have experience with these on a 996? I don't see a lot of P-car reviews on google searches. So, I figured I throw the question out there. Thanks in advance.

OP - First I’ve heard of Riaction. Have you found any 996 reviews? They might be good, might not. The Riaction advertised spring rates of 59/98nm (6kg/mm/10kg/mm) are Bilstein PSS spring numbers. BC Racing spring rates are 39/78 nm (50% stiffer than RoW M030 springs). All these Taiwanesium coils have the same design, parts bin, but different color schemes. Tear ‘em apart and they’re all nearly indentical. They won’t be rebuildable. I think you have to reuse the perches for all these cheaper coils. If the tubes all perform basically the same, then spring rates will definitely matter. Try them and let us know! Maybe you can work something out with Riaction. You can point out the lack of Porsche 996 reviews and your willingness to help them get the word out to us. Worst they can say is no. The price gap between the low and mid tier is now double! $1,500/$3,000/$4500+. Are you hell bent on coils? Get RoW M030 or Eibach Pro springs and Koni’s, call it a day. Fine for fun track and auto x days.

Definitely not hell bent on coilovers. I�d actually do not mind doing Konis and RoW springs. I�ve read a bit on this but have read differing reviews�some say Konis and RoWs and others say you can�t do RoWs with the Konis, that you can only do non RoWs. I just want a good ride quality with a lower stance but doesn�t have to be slammed or obnoxiously low�just tasteful and comfortable for street driving.

Cool. I waiver back and forth about coils. Several years back I put an adjustable rear sway and the Eibach springs on with my RoW B4 (M030) and really don�t need more. I track and cross it a few times a year and don�t get punished by daily street irregularities. The up side is this combo, or something like it, will last a long, long time. Middle of a GT4 sandwich.

In the same boat, been looking for coilovers. Main selling point for me is adjustability in ride height. Have you looked at the Silvers? Had them in the cart a few weeks looking for a better option at this price point and have not found one yet. https://silvers-na.com/products/silv...oaAijHEALw_wcB

BCR and Riaction are the same relabeled garbage with different anodizing. If you want to put that on your car just buy the cheapest one and be done with it.

Harsh .... but fair. With dampers/coilovers, you really do get what you pay for.

True� I have seen some positive BC reviews for our cars, which is why I figure I�d ask.

Feal 441 seem like the cheapest coil option that gets respect, and they are regarded pretty well at that. You are getting a whole set of shocks/springs for the than an axle worth of control arms on one of these cars. Maybe that means the money is better spent elsewhere, but it provides some context for what you are trying to improve upon as well.

The new Rennline 996 Coilovers look nice but haven�t seen any reviews as they are in the $1600-$1700 range.

It's possibly a cynical perspective, but a pair of Rennline's rear top mounts costs $494, and I'd imagine that the fronts would cost the same or possibly a bit more (to factor in the additional adjustability required) Granted they'll be a decent profit margin at those prices, but let's say they cost them $250 per end, or $500 for the fronts and rears. That makes your coilovers $1200 retail. Assuming the same profit margin as the top mounts, the cost price of 4 dampers and springs is $600 or $150 per damper and spring. I don't know about you guys, but there isn't much you can buy for $150 these days ... I'm not saying they're poor quality, but numbers is numbers, and the reality is that an adjustable damper with springs and spring seats, swaybar mounts etc, all for $150, something has to give bearing in mind the manufacturer has to make a profit too.

This is good stuff. There ate so many thoughts on coil overs, I definitely think this conversation is worth it and helpful to many. Reality is I will probably never track my car and the most aggressive driving I�ll do is to and from work in Los Angeles. Weekend drive up the coast or through a canyon is probably the most this car will see.

So I should correct myself, I was wrong. Riaction coilovers does not use Borr Chuan -- they are their own separate entity. https://www.104.com.tw/company/1a2x6...bsource=google Might be reasonable for the price.. might not. Someone has to find out For anyone who is interested in this sort of thing, there are websites like ImportYeti that allow you to see what companies use what suppliers. You can see some of the buyers of BC racing here (typical garbage like Megan, MeisterR (extra garbage), etc). https://www.importyeti.com/supplier/...ann-enterprise

You can do. What it boils down to is that the fully extended shock absorber must still hold the spring in place on its seat at either end of the spring. That will be the case with either RoW and non-RoW (=North American spec=M032=touring) springs with Konis. For a shorter spring that lowers the car, like M030, Koni does not offer a shock absorber (one with restricted rebound stroke) for the 996 like the yellow SP(ort) from the past. Get bilstein B8 for lowering springs and you're good. If you want a good ride and 'flat cornering' keep your springs and replace your shock absorbers with Koni Active ones. There is so much more to a good shock absorber than threaded bodies and anodized aluminium let you believe. The margins are so large that low price coil-overs still make the sellers of (chinese) manufactured ones money but they are of low quality (large variance between supposedly identical dampers, wear out quickly, oil that ages quickly, etc..). Spend your money wisely.

Get the Koni’s if you want a good street ride. Spend money on a better antiroll bar to help cornering.

So some H&R lowering springs and Konis sound like a good choice??

Lowering springs like H&R should use Bilstein B8 (equivalent valving as B6/M030 pack but with shorter shafts). Koni for OE height ride, or US M030, if you want capable but more compliant than B6 or B8.
